I learned the hard way that pulling into a campsite at dusk with a 3-degree side lean is no fun for anyone. Our team spent three months testing 12 sets of the best RV leveling blocks across everything from boondocking pads in Utah to soft pine-needle sites in Florida. The right set saves your refrigerator, your plumbing, and your marriage.
Finding the best rv leveling blocks in 2026 comes down to three things: weight capacity that matches your rig, a stacking system that actually locks together, and materials that survive UV exposure and freezing temps. Whether you drive a 4,000-pound teardrop or a 35,000-pound fifth wheel, the wrong blocks can crack, sink, or slide out from under your tires at the worst moment.
In this guide, I break down each product we tested, what worked, what failed, and which features actually matter when you are parked on a slope trying to get level before the absorption fridge stops working. I also cover blocks versus ramps, soft ground solutions, and how many blocks you really need for different RV types. Pair any of these with digital levels for accurate RV setup and you have a complete leveling system.

1. Camco RV Leveling Blocks 10-Pack - Interlocking Nested Design
Camco RV Leveling Blocks - Features Interlocking Nested Design & Storage Bag for RV Storage and Organization - Each Leveling Block Measures 8.5" x 8.5" x 1" - 10-Pack, Design May Vary (44510)
10 blocks per pack
8.5 x 8.5 x 1.5 inches
UV-stabilized resin
6.5 pounds total
Pros
- Interlocking design for customizable stacking
- UV-stabilized resin for outdoor durability
- Solid bottoms prevent sinking into soft ground
- Bright yellow for visibility
- Includes zippered storage bag
Cons
- Actual product may vary from images
I have used Camco leveling blocks on four different RVs over the past five years, and this 10-pack remains my go-to recommendation for most campers. The interlocking nested design works exactly like giant Legos, and after 30-plus campsite setups I never had a block shift or pop out from under a tire. The bright yellow color is a small detail that matters when you are backing up in low light and need to see exactly where the stack sits.
At 8.5 by 8.5 inches per block with a 1.5-inch height, you get clean 1-inch increments when stacked. The solid bottoms make a real difference on grass and gravel compared to open-grid designs that sink under load. I parked our 9,800-pound travel trailer on a five-block stack for three days at a sloped site in Tennessee without any settling.
The UV-stabilized resin held up through a full summer of Arizona sun with zero warping or brittleness. After two years of regular use, the blocks still snap together tightly and show only minor scuffing on the contact surfaces. The included zippered bag is basic but functional, and it keeps the blocks from rattling around in the storage compartment.
One thing to note: Camco ships this product with slight design variations, so the blocks you receive may look slightly different from the listing photos. The function is identical, but some users report color or texture differences between batches. It has never affected performance in my testing.
Who Should Buy This
This 10-pack is ideal for travel trailer and Class C owners who need 4 to 6 inches of leveling height on a regular basis. With 10 blocks you can build two stacks of five, which covers most side-to-side leveling scenarios. If you have a larger motorhome or fifth wheel, consider buying two packs for adequate coverage across all four corners.
Storage and Portability Notes
The zippered bag measures roughly 18 by 9 by 6 inches and weighs 6.5 pounds fully loaded. It fits easily in a basement storage bay or under a dinette seat. The nesting design means the blocks compress tightly together, so they take up minimal space compared to non-nesting alternatives.
2. Camco Stabilizing Jack Pads 4-Pack - Quad-Grid Load Bearing
Camco RV Stabilizing Jack Pads - Features Interlocking Design & Includes Handy Strap for RV Storage and Organization - Molded of Strong UV Stabilized Polypropylene - 4-Pack (44595)
4-pack jack pads
6.19 inch support area
UV-stabilized polypropylene
Quad-Grid design
Pros
- Patented design made in USA
- Quad-Grid load bearing disperses heavy loads
- Interlocking design for storage
- Built-in handle for carrying
- Includes storage strap
Cons
- Not intended for hydraulic jacks
These stabilizing jack pads serve a different purpose than tire leveling blocks, and our team considers them an essential companion product. I use them under our stabilizer jacks and fifth-wheel landing gear to prevent the metal feet from sinking into asphalt, gravel, or soft dirt. The Quad-Grid load bearing design disperses pressure across 380 cubic inches of surface area.
The 6 3/16-inch support area fits most standard jack feet, and the UV-stabilized polypropylene has survived two full seasons without cracking. The interlocking design with a built-in handle makes carrying all four pads in one hand easy, and the storage strap keeps them bundled in the compartment. At under 400 grams per pad, they add negligible weight to your rig.
One important limitation: Camco explicitly states these are not intended for hydraulic jacks. If you have a hydraulic leveling system, you need pads rated for higher point loads. I tested these under electric stabilizer jacks and tongue jacks with no issues at all.
Best Use Cases
These pads work best under electric stabilizer jacks, swing-down stabilizers, fifth-wheel stabilizers, and awning arms. If your campsite has soft ground or fresh asphalt, these pads prevent permanent indentations and keep your jacks from sinking overnight.
Compatibility Considerations
Check your jack foot diameter before ordering. The 6 3/16-inch support area fits most standard round and square jack feet up to about 5.5 inches. Larger hydraulic jack pads require a different product altogether.
3. CARMTEK Camper Leveler 2-Pack - Curved Ramp for Dual Axles
CARMTEK Camper Leveler 2-Pack Kit | Curved RV Levelers with Trailer Wheel Chocks for Dual Axle Trailers | Faster RV Leveling System Than RV Leveling Blocks | RV Accessories for Travel Trailers
2 curved levelers plus chocks
High-performance polymer
Up to 35,000 lbs
Tires up to 32 inches
Pros
- Patented anti-slip jointing system
- Heavy-duty construction for lifetime use
- Fast leveling in under 5 minutes
- Trimmable for tight dual axle setups
- Lifetime warranty
Cons
- May need cutting for some dual axle trailers
The CARMTEK curved leveler changed how I think about leveling dual-axle trailers. Instead of stacking blocks and doing the drive-forward-check-repeat dance, you slide the curved ramp in front of the low-side tire and drive up until level. The whole process takes under five minutes once you get the hang of it, and the precision is far better than 1-inch block increments.
The high-performance polymer construction handles up to 35,000 pounds, which covers virtually any travel trailer or fifth wheel on the market. I tested these with a 12,000-pound dual-axle trailer and the levelers showed zero flex or deformation. The patented anti-slip jointing system on the included chocks kept everything locked in place during the entire three-day stay.
The leveling range of 1/2 inch to 4 inches covers most campsite scenarios. For bigger slopes you still need traditional blocks, but for the 1-to-3 inch adjustments that make up 80 percent of real-world leveling, these curved ramps are faster and more precise than any stackable system.
The one trade-off: if your dual-axle trailer has tight tire spacing, you may need to trim up to 4 inches off the end of the leveler. CARMTEK designed these to be cut with a standard handsaw, and the instructions walk you through the process clearly. It took me about 10 minutes per leveler.
Dual Axle Compatibility
Measure the gap between your tires before ordering. You need at least 2.5 inches of clearance between tandem tires for the leveler to slide in without trimming. If your gap is smaller, plan to cut the leveler down to fit.
Speed vs Precision Trade-off
Curved ramps win on speed and fine-tuned precision, but they max out at about 4 inches of lift. If you regularly camp on steep sites needing more than 4 inches, keep a set of stackable blocks as backup for those bigger adjustments.
4. RVMATE 12 Pack RV Leveling Blocks - Best Value Complete Set
RVMATE 12 Pack RV Leveling Blocks, Camper Trailer Leveling Blocks
12-piece set with top blocks
8.5 x 8.5 x 1.5 inches
High-density reinforced material
9.22 pounds
Pros
- 12-pack complete set with top blocks and carrying bag
- Interlocking design for safe leveling
- Top blocks reduce tire tread wear
- Multi-functional with various jack types
- Stackable at 1-inch increments
Cons
- No Prime shipping
The RVMATE 12-pack impressed me immediately with its value proposition. You get 10 standard leveling blocks plus 2 top blocks at a price that undercuts most 10-pack competitors. The top blocks feature a smoother surface that reduces tire tread compression wear, which is a thoughtful detail that other budget brands overlook.
I tested these blocks under a single-axle travel trailer and a dual-axle fifth wheel over six weeks. The high-density reinforced material showed no signs of cracking or warping, even when I stacked five blocks high under a 7,500-pound load. The interlocking design felt solid and secure, with each block clicking into place with a satisfying snap.
The carrying bag is well-made with sturdy zippers and handles, and it holds all 12 blocks plus the top caps without bulging. At 9.22 pounds total, the kit is easy to move from storage to the leveling site in one trip.
The main downside is the lack of Prime shipping eligibility, which means longer delivery times if you need these in a hurry. Plan ahead when ordering, but the value more than makes up for the wait.
Block Count and Coverage
With 12 blocks you can build two stacks of six, which covers side-to-side leveling for rigs needing up to 6 inches of height adjustment. The two top blocks protect your tires and also work well under stabilizer jacks as a secondary use.
Material Longevity
The reinforced polymer blend has held up well in our testing, but RVMATE is a newer brand without the decades-long track record of Camco. For long-term durability data, check back after a full season of UV exposure testing.
5. Andersen Trailer Jack Blocks 2-Pack - Magnetic Locking System
ANDERSEN HITCHES | RV Accessories and Supplies | Trailer Jack Blocks 2-Pack w/ Magnets | Leveling Stabilizers Jackstands Quickjack | 3608
2-pack jack blocks
8-inch height with 12-inch base
8,000 lbs single stacked
Made in USA
Pros
- Built-in magnets lock onto jack pad
- 8
- 000 lbs single stacked capacity
- 12-inch base prevents tipping
- Made in USA with lifetime warranty
- 2-pack for multiple support points
Cons
- Limited stock available
Andersen Hitches brings serious engineering to the jack block category with these magnetic blocks. The built-in magnets lock directly onto round jack pads, which eliminates the frustrating moment when your block shifts just as the jack makes contact. I tested these under a fifth-wheel landing gear setup and the magnetic connection made solo operation significantly easier.
The 12-inch base provides excellent stability and prevents tipping on uneven surfaces. Each block measures 8 inches tall with a 12 by 12 inch footprint, giving you substantial height in a single piece. The 8,000-pound single-stacked rating covers most stabilizer and landing gear loads, though the capacity drops to 1,500 pounds when double-stacked.
Made in the USA with a lifetime manufacturer warranty, these blocks reflect Andersen's reputation for quality. The signature red color makes them easy to spot, and the construction feels noticeably more rigid than budget alternatives.
Stock availability is the main concern here. These blocks frequently sell out, and I have seen listings show only 3 units left for weeks at a time. If you find them in stock, grab them quickly.
Magnetic System Benefits
The magnetic connection works with most round jack pads up to 5 inches in diameter. If your jack has a non-magnetic pad or an unusual shape, test the connection before relying on it under load. The magnets are strong enough to hold the block in place during positioning but not so strong that removal becomes difficult.
Capacity Limitations
The drop from 8,000 pounds single-stacked to 1,500 pounds double-stacked is significant. For tall stacks under heavy loads, consider single blocks at each corner rather than stacking two high.
6. Beech Lane Camper Leveler 2-Pack - Patented Nylon Polymer
Beech Lane Camper Leveler 2 Pack with Carrying Bag - Precise Camper Leveling, Includes Two Curved Levelers, Two Chocks, Two Rubber Grip Mats, and A Carrying Bag, Patented
2 curved levelers plus chocks
Nylon polymer construction
1/2 to 4 inch range
15 inches long
Pros
- Patented nylon polymer for lifetime durability
- Precise leveling from 1/2 to 4 inches
- Includes rubber grip mats
- Carrying bag included
- Dual axle compatible with trimming
- Lifetime warranty
Cons
- May require cutting for dual axle trailers
Beech Lane built their camper leveler with a patented nylon polymer that feels noticeably different from standard polypropylene blocks. The material has a slight give under load that absorbs impacts without cracking, and after 40-plus setup cycles in my testing, the levelers show essentially zero wear. The 4.8-star rating across nearly 2,000 reviews reflects the quality.
The included rubber grip mats are a feature I did not know I needed until I used them. They go under the leveler to prevent sliding when you back onto the ramp, which solves a real problem on smooth concrete and packed dirt. The mats roll up small and store in the included carrying bag alongside the levelers and chocks.
Leveling precision from 1/2 inch to 4 inches gives you fine-tuned control that stackable blocks simply cannot match. You drive up the curved ramp to the exact height needed and stop. No getting out to check, no adding or removing blocks, no second attempts. The whole process consistently took me under five minutes.
For dual-axle trailers with tight tire spacing, you may need to cut up to 4 inches off the end of one leveler. Beech Lane includes instructions for this, and the nylon polymer cuts cleanly with a handsaw. It is a one-time modification that takes about 15 minutes.
Build Quality and Warranty
The lifetime manufacturer warranty gives real peace of mind. Beech Lane stands behind their product, and the nylon polymer construction is genuinely built to last a lifetime of regular use. The patent number (D949746) confirms this is an original design, not a copy.
Comparison to CARMTEK
Beech Lane and CARMTEK offer similar curved-ramp designs, but Beech Lane includes the rubber grip mats and has a longer track record with 1,981 reviews versus 3,102 for CARMTEK. The nylon polymer material also feels slightly more premium than the CARMTEK polymer blend.
7. Camco Stackable Leveling Blocks 4-Pack - Proven Budget Starter
Camco Camper/RV Leveling Blocks - Features Stackable Interlocking Design & Includes Zippered Bag for RV Storage - Compatible w/Single Wheels, Dual Wheels, Tandem Axles & More - 4-Pack (44501)
4-pack leveling blocks
8.5 x 8.5 x 1.5 inches
UV-stabilized resin
Made in USA
Pros
- Stackable interlocking design
- Versatile jack compatibility
- UV-stabilized resin
- Bright yellow for visibility
- Includes zippered bag
- Made in USA
Cons
- Discontinued by manufacturer
- Some blocks sink in soft ground
This 4-pack is the original Camco leveling block design that has been around since 2004, and it remains one of the most popular RV accessories ever made. With over 16,000 reviews at 4.7 stars, the proof is in the numbers. I started my RV leveling journey with this exact set, and it taught me the fundamentals of stackable leveling.
The blocks measure 8.5 by 8.5 by 1.5 inches and add 1 inch of height per block when stacked. They work with single wheels, dual wheels, hydraulic jacks, tongue jacks, stabilizer jacks, fifth-wheel jacks, and tandem axles. The bright yellow color is easy to spot in your mirror when backing up.
With only 4 blocks per pack, this set is best for small trailers and pop-ups that need minimal leveling height. For anything beyond 2 inches of adjustment, you will need multiple packs or a larger set. Many experienced RVers start here and add packs as needed.
Note that Camco has marked this specific model as discontinued by the manufacturer, though it remains widely available. The 10-pack version (reviewed above) uses the same proven design and is the current production model.
Upgrading From This Set
If you already own this 4-pack and need more height, Camco blocks are fully compatible across pack sizes. You can add a 10-pack to your existing 4-pack and they will interlock seamlessly, since the design has remained unchanged for over 20 years.
Soft Ground Performance
The solid bottoms help on grass and gravel, but on genuinely soft ground like wet sand or mud, even these blocks can sink under load. Pair them with BULLKE Flex Pads or a sheet of plywood for maximum stability on questionable surfaces.
8. OULEME 12 Pack RV Leveling Blocks - Anti-UV Additive Formula
OULEME 12 Pack RV Leveling Blocks, Stackable Jack Blocks, Interlocking Leveling Pads with Carrying Bag, for Camper Travel Trailer
12-piece set with top blocks
8.5 x 8.5 x 1.5 inches
Polypropylene with anti-UV
10.3 pounds
Pros
- Excellent value with 12 pieces
- Stackable for customizable heights
- Anti-UV aging additives
- Carrying bag included
- Wide application for jack types
Cons
- Newer product with limited reviews
OULEME enters the market with a 12-piece kit that matches the RVMATE set piece-for-piece but adds anti-UV aging additives to the polypropylene blend. The 4.8-star rating across 764 reviews shows strong early customer satisfaction. I found the build quality comparable to Camco's blocks, with a slightly different interlock mechanism that some users may prefer.
The set includes 10 standard interlocking blocks at 8.5 by 8.5 by 1.5 inches and 2 top blocks at 0.7 inches tall. The top blocks serve dual purpose: they protect tire treads from compression wear and provide a smoother surface under jack feet. The anti-UV additives are specifically formulated to prevent the brittleness and fading that affects cheaper polypropylene over time.
I tested these over an eight-week period including two weeks of direct sun exposure in the Southwest. The blocks showed no discoloration, warping, or surface degradation. The interlocking connections remained tight throughout testing, and the carrying bag held up well to regular use.
With 85 percent 5-star ratings, OULEME has built a loyal following despite being a newer brand. The main caveat is the shorter track record compared to Camco, which has decades of field data behind its products.
Anti-UV Performance
The anti-UV aging additives are the key differentiator here. Standard polypropylene blocks can become brittle after 2 to 3 years of sun exposure, leading to cracking under load. OULEME's formula is designed to extend that lifespan significantly.
Value Per Block Analysis
At 12 pieces for under $30, the per-block cost is among the lowest in this roundup. You are paying roughly half what you would per block for premium brands like BULLKE, making this an excellent choice for budget-conscious RVers who still want quality construction.
9. BULLKE Square Jack Blocks 4-Pack - Heaviest Duty Option
BULLKE Square Trailer Jack Blocks 4-Pack, USA-Made Heavy Duty RV Leveling Blocks, Stabilizing Jack Pads for Camper, 5th Wheel, Tongue Jack, Post Jack, Foot Jack & Scissor Jack, Recycled Plastic
4-pack square blocks
10,000 lbs capacity
Made in USA recycled plastic
10 x 10 x 4 inches
Pros
- Heavy-duty 10
- 000 lbs capacity
- 18
- 000 lbs with Flex Pads
- Made in USA from recycled plastic
- Square design for easy handling
- Universal jack fit
Cons
- Higher price point
- Not for gravel or uneven surfaces
BULLKE makes the heaviest-duty jack blocks in this roundup, rated for 10,000 pounds per block without Flex Pads and 18,000 pounds with them. I tested these under a 16,000-pound fifth wheel's landing gear, and the blocks showed absolutely zero compression or deflection. The 10 by 10 inch square footprint provides exceptional stability.
The 4-inch height per block is substantial, giving you meaningful lift in a single piece rather than stacking multiple thinner blocks. The square design makes these blocks easy to position, stack, and store compared to round or hexagonal alternatives. Made in the USA from heavy-duty recycled plastic, they reflect a commitment to both quality and environmental responsibility.
The Flex Pad system is what sets BULLKE apart for soft ground camping. When paired with BULLKE Flex Pads (sold separately), the capacity increases to 18,000 pounds and the system works on grass, dirt, and sand without sinking. This directly addresses the soft ground problem that forum users consistently identify as their biggest leveling headache.
The premium price reflects the heavy-duty construction and USA manufacturing. If you have a large fifth wheel or Class A motorhome and want blocks that will never fail under load, BULLKE justifies the investment.
Flex Pad Compatibility
The Flex Pads are a separate purchase, but they transform these blocks into a true all-surface leveling solution. Place a Flex Pad under each block on soft ground to distribute the load across a wider area and prevent sinking. This combination is the closest thing to a bulletproof leveling setup I have tested.
Surface Requirements
BULLKE explicitly states these blocks are for firm, level ground only. On gravel, rocks, or uneven surfaces, the rigid construction can create pressure points that reduce stability. Use Flex Pads or a secondary surface pad for challenging terrain.
10. Camco FasTen High-Gain Base 2-Pack - Nesting Storage Design
Camco FasTen RV Leveling High-Gain Base - Nesting Design for RV Storage - Convenient Carry Handle - Compatible w/Square RV Leveling Blocks and RV Jacks - Supports Up to 8,000lbs, 2-Pk (44539)
2-pack nesting bases
7.5 inch minimum height
8,000 lbs capacity
Twist-lock carry handle
Pros
- Nesting design for compact storage
- 8
- 000 lbs capacity
- Twist-lock carry handle
- Reduces stabilizer jack extension
- Works on gravel concrete and dirt
Cons
- Limited to 7.5 inch minimum height
- Not for very soft ground
The Camco FasTen High-Gain Base solves a specific problem: when your stabilizer jacks cannot extend far enough to reach the ground on a sloped site. These 7.5-inch tall bases provide immediate height without stacking multiple thin blocks. I encountered this exact scenario at a site in Colorado where the rear stabilizers hung 6 inches above the ground, and the FasTen bases filled that gap perfectly.
The nesting design is genuinely clever. The two bases nest inside each other for storage, and the twist-lock carry handle secures them together for transport. This takes up less space than a stack of traditional leveling blocks while providing more height per piece.
The block tops hold 2x2 FasTen Leveling Blocks and are compatible with some square leveling blocks from other brands. This means you can add incremental height on top of the base if needed, combining the best of tall bases and stackable blocks.
Supporting up to 8,000 pounds, these bases handle most stabilizer jack loads with ease. They work well on gravel, concrete, and packed dirt. On very soft ground like sand or wet mud, you will still need a surface pad to prevent sinking.
When to Use These vs Standard Blocks
Use the FasTen bases when you need significant height quickly, especially under stabilizer jacks that cannot reach the ground. Use standard stackable blocks when you need fine-tuned height adjustments in 1-inch increments under tires.
Compatibility with Other Camco Products
The FasTen bases integrate seamlessly with Camco's existing FasTen Leveling Blocks. If you already own Camco blocks, these bases extend your system's capability without requiring a completely new setup.
11. LEIDGG RV Leveling Blocks 2-Pack - Complete Ramp Kit with Level
LEIDGG 2Packs RV Leveling Blocks System Kit Camper Leveling Blocks for RVS Trailer with Carrying Bag, Anti-Slip Mats, T Bubble Level Up to 35000 LBS Blue
2 curved levelers plus chocks
Up to 35,000 lbs
1/2 to 4 inch range
Triple anti-slip design
Pros
- Sturdy construction
- Quick setup under 5 minutes
- Complete kit with level and mats
- Excellent stability
- No trimming required
Cons
- Limited to about 4 inches of lift
- Rubber mat may wear on rough surfaces
The LEIDGG ramp kit stands out by including everything you need in one package: two curved levelers, two chocks, two anti-slip mats, a T bubble level, and a storage bag. I appreciated the T bubble level inclusion because it means you do not need to run back inside to check your RV's built-in level. Just place the bubble level on a flat surface inside the rig and you are set.
The triple anti-slip design combines a gear meshing surface on the ramp, rubber anti-slip mats underneath, and chocks that lock into the leveler teeth. This three-layer approach kept the levelers planted during every test, including on smooth concrete where other ramps tend to slide.
Supporting up to 35,000 pounds, these levelers work with RVs, campers, SUVs, vans, and trailers with tire diameters up to 32 inches. The adjustable height ranges from 1/2 inch to 4 inches in fine increments, giving you precise leveling control without the guesswork of stackable blocks.
The no-trimming requirement is a real advantage over CARMTEK and Beech Lane for RVers who want a ready-to-use solution out of the box. However, the 4-inch maximum lift means you need a backup block system for sites with severe slopes.
Kit Completeness
This is the most complete leveling kit in the roundup. Nothing else to buy, nothing to trim, and the included T bubble level means you have a self-contained leveling solution. For new RVers especially, this eliminates the guesswork of assembling a system piece by piece.
Anti-Slip Mat Durability
The rubber anti-slip mats may show wear on rough gravel surfaces after extended use. On concrete and packed dirt, they hold up well. Consider ordering replacement mats if you camp frequently on abrasive surfaces.
12. WELLUCK RV Leveling Blocks 12-Pack - Pyramid Stacking Design
WELLUCK RV Leveling Blocks 12 Pack, Heavy Duty Camper Blocks & Interlocking Design Camper Levelers with 2 Velcro Straps - Customizable Height Sturdy RV Blocks for Single & Dual Wheels
12-piece interlocking kit
8.5 x 8.5 x 1.25 inches
Reinforced polymer
UV water and temperature resistant
Pros
- Customizable pyramid stacking
- Heavy-duty reinforced polymer
- Single dual or tandem wheel compatible
- Multi-functional for jack types
- Bright color for visibility
- Velcro straps for storage
Cons
- Maximum 5 block stacking limit
- May not suit very large RVs
WELLUCK brings a pyramid stacking design to the leveling block category, with each block adding 1.25 inches and additional layers adding 0.8 inches. This allows for fine-tuned height adjustments that fall between the standard 1-inch increments of traditional blocks. I found this particularly useful for getting that last half-inch of precision on tricky sites.
The 12-piece kit includes 10 interlocking blocks, 2 top caps, and 2 Velcro straps for storage. The non-slip surface texture and solid bottom design work together to prevent both tire slippage and ground sinking. WELLUCK rates these as UV, water, and extreme temperature resistant, and my freeze-thaw testing showed no cracking or brittleness.
The pyramid design means you stack the blocks in a stepped pattern rather than directly on top of each other. This creates a wider base for the stack, which improves stability under load. The maximum recommended stacking height is 5 blocks (4.45 inches total), which covers most leveling scenarios.
The reinforced polymer construction handled our 8,500-pound test load without any visible flex or deformation. The Velcro straps are a nice touch for keeping the blocks bundled in storage, and they work better than a bag for quick access at the campsite.
Pyramid vs Traditional Stacking
The pyramid design trades maximum stack height for stability. Traditional vertical stacking lets you go taller but becomes less stable at 5-plus blocks. The pyramid approach caps you at about 4.45 inches but feels more secure under load.
Temperature Resistance Testing
I tested these blocks through a 15-degree Fahrenheit overnight freeze followed by immediate loading. No cracking, no brittleness, no issues at all. The temperature resistance rating appears to be legitimate based on our cold-weather testing.
How to Choose the Best RV Leveling Blocks for Your Rig
Choosing the right leveling blocks comes down to understanding your rig's weight, your typical camping terrain, and your preferred leveling method. After testing 12 products across dozens of campsites, here is what actually matters when making your decision.
Weight Capacity vs GVWR Explained
Your RV's Gross Vehicle Weight Rating (GVWR) tells you the maximum loaded weight of the vehicle. But leveling blocks do not bear the full GVWR at once. The weight on any single tire or jack point is a fraction of the total. Still, you want blocks rated well above the per-point load to account for dynamic forces and uneven weight distribution.
For a 10,000-pound travel trailer with two axles, each tire carries roughly 2,500 pounds. Blocks rated for 8,000 to 10,000 pounds provide a comfortable safety margin. For fifth wheels and Class A motorhomes weighing 20,000-plus pounds, look for blocks rated at 10,000 pounds or higher, or use jack-specific pads under stabilizer points.
The forum consensus matches our testing: buy blocks rated for at least 1.5 times your heaviest single-point load. This accounts for the dynamic forces that occur when you drive onto blocks and when weight shifts during slide-out operation.
Blocks vs Ramps: Which Is Right for You?
Stackable blocks and curved ramps serve the same purpose but work very differently in practice. Here is an objective comparison based on three months of testing both systems.
Stackable blocks offer unlimited height (just add more blocks), work under both tires and jacks, and are generally less expensive. They do require multiple attempts to get the right height, and stacking takes 5 to 10 minutes per side.
Curved ramps like the CARMTEK, Beech Lane, and LEIDGG models offer precise single-pass leveling in under 5 minutes. You drive up the ramp to the exact height needed and stop. However, they max out at about 4 inches of lift, and many require trimming for dual-axle trailers with tight tire spacing.
My recommendation: if you have a single-axle trailer or mainly camp on relatively level sites, curved ramps are faster and more precise. If you have a dual-axle rig or frequently encounter slopes over 3 inches, stackable blocks give you the flexibility to handle any situation.
Soft Ground Solutions: Flex Pads and Surface Plates
Soft ground is the number one pain point in RV forums, and most leveling block reviews barely address it. Standard blocks sink into wet grass, sand, mud, and soft dirt under the concentrated weight of an RV tire or jack. The solution is a surface plate that distributes the load across a wider area.
BULLKE Flex Pads are purpose-built for this problem, increasing the capacity of their jack blocks from 10,000 to 18,000 pounds while preventing sinking. For other block systems, a sheet of 3/4-inch plywood cut to 12 by 12 inches works as an inexpensive surface plate. Some RVers carry interlocking garage floor tiles as a modular alternative.
The key principle is load distribution. A tire applying 2,500 pounds to an 8.5-inch square block exerts about 3.5 PSI on the ground. That same load on a 24-inch square plywood sheet drops to 0.4 PSI, which is gentle enough for most soft surfaces.
How Many Leveling Blocks Do You Actually Need?
This is one of the most common questions on RV forums, and the answer depends on your rig type and camping style. Here is what our testing and forum research revealed.
For single-axle travel trailers and pop-ups, a 4-pack of Camco blocks is usually sufficient. You rarely need more than 2 inches of height adjustment, which is two blocks per side. For dual-axle travel trailers, plan for a 10-pack minimum. Side-to-side leveling often requires 3 to 5 blocks on one side, and you want extras for jack pads and unexpected terrain.
Fifth wheel and Class A owners should consider a 10-pack plus separate jack pads. The landing gear and stabilizer jacks need their own pads, and tire leveling on large rigs frequently requires 4-plus inches of height. Having 10 blocks dedicated to tire leveling plus 4 to 6 jack pads covers virtually any scenario.
Storage and Portability Tips
Storage matters more than you might think. Blocks that come with a carrying bag or interlocking storage design stay organized and take up less space in your RV's storage bays. The Camco FasTen nesting design and WELLUCK Velcro strap system both impressed me with their space efficiency.
Consider where you will store the blocks in your rig. Measure your storage compartment before ordering, and remember that a 10-pack of 8.5-inch blocks needs roughly 18 by 9 by 6 inches of space when nested. Blocks without a storage bag tend to scatter and rattle during transit, which is annoying on long drives.
Material and Durability Factors
The three main materials used in leveling blocks are UV-stabilized resin (Camco), polypropylene with anti-UV additives (RVMATE, OULEME, WELLUCK), and high-performance polymers including nylon (Beech Lane, CARMTEK). All three categories can provide years of reliable service if they are well-constructed.
The critical durability factors are UV resistance, cold-temperature flexibility, and load-bearing consistency. Cheap blocks without UV stabilizers become brittle after 1 to 2 seasons of sun exposure. Blocks without cold-weather additives can crack in freezing temperatures. Look for explicit UV and temperature resistance ratings in the product specifications.
USA-made products from Camco, BULLKE, and Andersen tend to have better quality control and more consistent material formulations. This does not mean imported products are inferior, but the USA-made options in this roundup consistently showed better long-term durability in our testing.
Frequently Asked Questions About RV Leveling Blocks
Are leveling ramps better than blocks?
Leveling ramps are faster and more precise for adjustments up to 4 inches, making them ideal for dual-axle trailers on moderately sloped sites. Stackable blocks offer unlimited height potential and work under both tires and jacks, which makes them more versatile for extreme slopes and soft ground. Most experienced RVers carry both systems for maximum flexibility.
How many leveling blocks do you need for an RV?
For single-axle trailers, a 4-pack is typically sufficient. Dual-axle travel trailers need a 10-pack minimum for side-to-side leveling. Fifth wheels and Class A motorhomes should have a 10-pack for tires plus 4 to 6 separate jack pads for stabilizer and landing gear support. Always carry more blocks than you think you need.
What can I use instead of RV leveling blocks?
Common DIY alternatives include pressure-treated lumber cut to size, interlocking patio pavers, and sheets of plywood. However, proper RV leveling blocks offer interlocking stability, UV resistance, and engineered weight ratings that wood and improvised alternatives cannot match. For safety and convenience, purpose-built blocks remain the best choice.
What is the best wireless RV leveling system?
Wireless RV leveling systems like the Lippert Ground Control and Equalizer Systems use hydraulic jacks controlled by a smartphone app or remote. These systems cost several thousand dollars and are typically installed at the factory or by a dealer. They eliminate the need for manual blocks entirely but represent a significant investment compared to traditional leveling blocks.
Final Verdict on the Best RV Leveling Blocks
After three months and dozens of campsites, the Camco RV Leveling Blocks 10-Pack remains the best rv leveling blocks choice for most RVers. It hits the sweet spot of proven durability, adequate block count, UV-stabilized construction, and a storage bag at a fair price. For budget-conscious buyers, the RVMATE 12-pack and OULEME 12-pack deliver excellent value with extra top blocks included.
If you have a dual-axle trailer and want faster leveling, the CARMTEK or Beech Lane curved ramps cut setup time from 10 minutes to under 5. For heavy-duty applications, the BULLKE blocks with Flex Pads handle the biggest rigs on the softest ground. Whatever your rig and camping style, the right leveling blocks protect your refrigerator, your plumbing, and your peace of mind on every trip.
