1. Camco Interlocking Leveling Blocks
Best for: General RV leveling and stabilization needs.
The Camco Interlocking Leveling Blocks feature a nested design that allows you to reach your desired height by adding one inch per block. The bright yellow color is a practical touch that helps you spot them against the ground, reducing the risk of leaving them behind at the campsite.
Because they’re made from UV-stabilized resin, these blocks can handle long-term exposure to the sun without degrading quickly. The solid bottom design is a critical feature; it prevents the blocks from sinking into soft ground, which is often where standard plastic supports fail.
If you’re parking on soft dirt or gravel, use these blocks to create a stable base for your tongue jacks, stabilizer jacks, or tandem axles. However, if you’re operating a massive fifth-wheel rig, check your vehicle’s weight requirements first. These blocks are built for standard travel trailers and RVs.
Pros
- Bright color prevents accidental loss.
- Easy to clean with a hose.
- Included zippered bag simplifies storage.
- Solid bottoms prevent sinking into soft ground.
Cons
- May not suit heavy-duty industrial needs.
- Design may vary slightly due to continuous product updates.
2. Camco Stackable Leveling Blocks
Best for: Compact storage in smaller travel trailers.
These blocks offer the same interlocking convenience as larger kits but in a four-pack, making them perfect for owners with limited storage space. Each block adds exactly 1″ to your stack height. If you face a significant slope, you’ll likely need more than one four-pack to achieve a level rig.
The patented design is manufactured in the USA, which appeals to buyers looking for domestic production. These blocks are compatible with single wheels, dual wheels, and various jacks, including tongue and stabilizer jacks. The solid bottom construction prevents sinking into soft ground, which is a common failure point for lighter supports.
If you’re camping on soft grass or dirt, place these blocks directly under your jacks to maintain stability. When you finish, simply hose them down to remove debris. Their bright yellow color ensures you spot them easily before driving away, preventing the common mistake of leaving gear behind at the campsite.
Pros
- Very compact for easy storage.
- Works with many jack types.
- Durable, UV-stabilized resin build.
Cons
- Limited height for uneven terrain.
3. RV Leveling Blocks 12-Pack
Best for: Campers requiring extra stability on soft ground.
This 12-pack is a comprehensive kit that includes ten standard blocks and two rubber-top blocks for added grip. The polypropylene material is treated with anti-UV additives, which keeps the plastic from becoming brittle after seasons of use in direct sunlight.
The rubber tops provide more friction than standard plastic, which makes a difference when parking on slick surfaces. Arrange these in a pyramid shape to reach the specific height your RV requires before driving onto the stack. If you notice your RV swaying while eating or sleeping, these blocks provide the base support needed to keep your trailer balanced.
If you have a very small, lightweight trailer, you might find that 12 blocks are more than you actually need to carry, taking up extra room in your storage bay. However, for larger rigs, the full set ensures you have enough pieces to support both the wheels and your jack stands simultaneously.
Pros
- Rubber tops increase ground grip.
- Large set covers most needs.
- UV-resistant material lasts longer.
Cons
- May be bulky for small rigs.
4. BUNKER INDUST RV Leveling Blocks/Stackable Jack Blocks
Best for: Heavy-duty support for larger trailers.
These blocks are built for strength, supporting loads up to 15,000 lbs while remaining relatively light at 7.7 lbs. The dual-purpose design means you can use them under your tires for leveling or under your stabilizer jacks for added height.
The polypropylene construction is resistant to extreme temperatures, which is excellent if you travel between very hot and very cold climates. Because these are built for high weight, they might feel like overkill for a pop-up camper owner who only needs minimal height adjustment.
Pros
- High weight capacity for safety.
- Weather-resistant material construction.
- Versatile for jacks and tires.
Cons
- Might be unnecessary for ultralight rigs.
5. MaxxHaul 50955 High Visibility RV Leveling Blocks With Interlocking Nested
Best for: Campers who want to avoid losing gear.
The MaxxHaul system uses an interlocking nested design for quick deployment. You arrange the 8.5-inch by 8.5-inch blocks in a pyramid shape to reach a maximum lift of 4 inches. These modular units are adaptable to any leveling task and serve as a stable base for your other stabilizing equipment.
The bright color scheme is a major highlight, ensuring you can find them in grass or gravel after packing up. If you’re leveling on a slight slope, these blocks provide the necessary support. However, if your campsite sits on a steep incline, the maximum height capacity won’t suffice. In those cases, you must look for alternative equipment to achieve the required elevation.
The 10-pack comes with a zippered storage bag for easy transport when not in use.
Pros
- Easy to see in grass.
- Simple pyramid stacking method.
- Includes convenient storage bag.
Cons
- Maximum height is limited.
6. CARMTEK Camper Leveler Premium Kit
Best for: Fast and precise leveling on a slope.
The CARMTEK system replaces flat blocks with a curved design that allows for infinite adjustment between 1/2 inch and 4 inches. This is much faster than stacking blocks, as you simply drive onto the leveler until the trailer is perfectly horizontal.
The high-performance polymer is built to last, supporting trailers up to 35,000 pounds with tires up to 32 inches in diameter. The included chocks lock into the leveler using a patented anti-slip jointing system. Because the grip channels align with chock notches based on the vehicle’s weight, heavier trailers actually increase the system’s stability.
If you have a trailer with dual axles, measure the space between your tires before installation. If that gap is less than 2.5 to 3 inches, you must trim a portion off the leveler to ensure a proper fit. Failing to check this clearance can prevent the unit from seating correctly between the wheels.
Pros
- Faster than stacking blocks.
- Precise leveling at any height.
- Lifetime warranty included.
Cons
- May require trimming for tight axles.
7. Beech Lane Camper Leveler 2 Pack with Carrying Bag
Best for: Owners who prioritize precision.
Beech Lane uses an exceptionally strong nylon polymer designed to prevent the compression or cracking that can occur with standard plastics. The kit includes rubber grip mats that sit under the levelers, which is a big help on concrete or hard-packed dirt. These mats stop the units from sliding away as you back your tires onto them.
This system is great for achieving a level rig in under five minutes, reducing the frustration of repeated backing and stopping. You can dial in your height at any increment from the minimum to the maximum lift.
Check your axle spacing before buying. If you have a dual-axle trailer, measure the gap between your tires. If that space is less than 2.5 to 3 inches, you must cut a portion off the end of one leveler to make it fit. This modification doesn’t affect the structural integrity of the nylon polymer.
Pros
- Durable nylon polymer construction.
- Includes anti-slip rubber mats.
- Lifetime manufacturer warranty.
Cons
- Trimming needed for tight axles.
8. Trailer Jack Block
Best for: Stabilizing tongue jacks.
This single block handles the heavy weight of a tongue jack or fifth-wheel landing gear. It’s rated for 40,000 lbs, making it a robust option for heavy-duty stabilization. The polymer construction includes anti-UV additives to resist oil, grime, and environmental aging over years of use.
The built-in rope and side handle make it easy to carry, despite its solid design. If you need to level tires, don’t use this block. It’s shaped specifically for jack feet, round or square posts, and scissor stabilizers. Using it under tires won’t provide the surface area required for safe leveling.
Because the blocks are stackable, you can adjust the height to achieve a level camper on uneven ground. Each unit measures 11.5 inches square and 6 inches tall. If you’re unsure about the fit for your specific jack type, contact the manufacturer directly for guidance.
Pros
- Massive weight capacity for jacks.
- Easy to carry with rope.
- Resists oil and grime.
Cons
- Not for tire leveling.
9. RV Leveling Blocks System
Best for: Heavy-duty tire leveling.
This system uses a curved design to provide gradual lift for tires up to 32 inches in diameter. You can drive forward to achieve a precise height within the system’s range in just minutes. The gear mesh design allows the chocks to lock firmly into the leveler, which provides a secure base for your trailer.
If you’re parking on soft soil, place the included rubber pads beneath the levelers to ensure stability. While traditional wooden blocks are heavy and cumbersome, these UV-resistant materials are built for long-term performance in extreme weather.
If your vehicle has a G.V.W. up to 35,000 pounds, this system is rated to handle the load without trimming. However, if you prefer the simplest gear possible, remember that this system requires more steps than basic stackable blocks. You must properly align the gear mesh to ensure the chocks lock. Failing to seat the chocks fully can compromise stability on uneven ground.
Pros
- Supports up to 35,000 pounds.
- Secure gear-mesh locking design.
- Includes anti-slip mats.
Cons
- Requires precise chock alignment.
10. RV Leveling Blocks 12-Pack
Best for: Organized storage enthusiasts.
The WELLUCK 12-pack includes Velcro straps, making it significantly easier to keep blocks bundled than throwing loose pieces into a storage bay. Each base block adds 1.25 inches of lift, while adding subsequent layers increases your height by 0.8 inches per block. This allows you to build a stable, pyramid-style stack tailored to your specific terrain.
The reinforced polymer construction resists UV rays, water, and extreme temperatures, preventing the cracking often seen in standard plastic alternatives. While the blocks are versatile enough for trailer, tongue, or stabilizer jacks, don’t exceed the five-block limit. Stacking beyond this height compromises structural integrity, as the maximum recommended lift is 4.45 inches.
If you’re parking on soft ground, the solid bottom design prevents sinking, but always ensure your directional arrows are aligned before driving onto the stack. Use the bright color to your advantage; it prevents you from accidentally leaving blocks behind when breaking camp.
Pros
- Includes Velcro straps for bundling.
- High-density reinforced polymer material.
- Good height per block.
Cons
- Stacking height limit applies.
How to Choose Leveling Blocks and Storage Bags
Which type of leveling system is actually better?
The choice between stackable blocks and curved levelers depends on your patience and your rig’s needs. Stackable blocks are the classic, versatile choice; you can use them for tires, tongue jacks, and stabilizers. However, they require you to guess the stack height and drive on and off multiple times. Curved levelers are faster and more precise, allowing you to stop exactly when the spirit level shows you’re flat. If you have dual axles, curved levelers might require trimming to fit between the tires, whereas blocks work with almost any wheel configuration. Always check the Occupational Safety and Health Administration guidelines for heavy equipment handling to ensure you’re using your blocks on stable, flat ground.
Do I need to worry about the material quality?
Yes, material quality is the most important factor for long-term use. Look for terms like “UV-stabilized,” “high-density polymer,” or “nylon polymer.” These materials are designed to resist the sun’s rays and maintain their shape under pressure. Always prioritize blocks that mention high weight ratings or specific structural polymers to ensure they don’t sink or break when you’re camping on soft or uneven ground.
What should I confirm before buying?
Before you hit the buy button, check your RV’s weight and your axle configuration. If you have a heavy fifth-wheel, you need to ensure your blocks or jack pads are rated for that specific load. For those with dual axles, measure the distance between your tires. Some curved levelers require at least 2.5 to 3 inches of space to fit properly without cutting the product. If you have less space, you must be prepared to trim the leveler, or you should stick with traditional interlocking blocks. Finally, confirm that the kit includes a storage bag. Buying a bag separately is an extra expense and often leads to a poor fit for your specific blocks.
Frequently Asked Questions
What goes wrong with these blocks first?
Leveling blocks often crack or crush when placed on uneven, rocky surfaces that leave them unsupported. The bright yellow color helps prevent losing individual blocks at the campsite. However, blocks without UV stabilization can become brittle and fail after prolonged sun exposure.
Is the simplest leveling block kit enough for my needs?
A 10-pack of interlocking blocks is sufficient for standard campsite slopes and versatile enough for both tires and stabilizer jacks. These basic sets work well on level pads. For boondocking on uneven terrain, you may prefer a curved leveler or a set with rubber grips for added stability.
What should I look for in a storage bag?
A storage bag for leveling gear should feature durable, tear-resistant material and a reliable, easy-to-clean zipper. Ensure the bag is spacious enough to hold the blocks comfortably without straining the closure. Sturdy handles are essential for carrying the heavy, mud-covered blocks from your storage bay to the campsite.
Closing
Choosing the right storage solution protects your gear and keeps your RV bay clutter-free. For most owners, interlocking blocks like those from Camco or ROBLOCK provide the best balance of visibility and modular height adjustment. Arrange these in a pyramid shape to reach your required lift, ensuring you don’t exceed the manufacturer’s recommended stack limit, which is often five blocks.
If you travel frequently or operate a heavier rig, consider curved leveling systems like the CARMTEK or Beech Lane kits. These allow for precise leveling in any increment within the system’s range in under five minutes. If you choose this route for a dual-axle trailer, check your tire spacing first. If the gap is less than 2.5 inches, you may need to trim the leveler to fit, a process that doesn’t affect performance.
Always verify your trailer’s weight against the system’s capacity, which can range from 15,000 to 40,000 lbs. Selecting the right gear now ensures you spend more time enjoying your trip.
