RVMATE 12 Pack RV Leveling Blocks

RVMATE’s 12-pack leveling blocks are designed to stabilize RVs and trailers on uneven ground. They use high-density reinforced materials and an interlocking design to secure the vehicle during leveling. The blocks measure 8.5″ x 8.5″ x 1.5″ with top blocks at 0.75″ thick, allowing stacking to meet various height needs. A two-piece top cover helps minimize tire contact with the block body, reducing wear. This setup supports single and dual-wheel configurations and aims to reduce trailer movement when parked.
Features in focus include level-and-stabilize performance, sturdy construction, and stackable versatility. The interlocking design supports safer, quicker leveling, while the top covers help preserve tire tread and block integrity during use.
Camco FasTen XL Camper/RV Leveling Blocks

Camco FasTen XL blocks are designed for customizable height with an interlocking system. The 10-pack stacks to achieve the desired support, and the premium integrated T-handle aids carrying and secure storage. Each block measures 10.5″ x 10.5″ x 1.5″, and the quad-grid design is built for high load capacity. The system emphasizes stability for RVs and campers, with easy assembly and disassembly for transport and storage.
Key considerations include compatibility with various jack configurations and the balance between stack height and overall stability. The integrated handle and interlock mechanism contribute to efficient setup and dependable support on diverse terrains.
CARMTEK Camper Leveler Premium Kit

The CARMTEK Premium Kit features a patented anti-slip jointing system between levelers and wheel chocks to prevent sliding. It uses a high-performance polymer designed to withstand trailer weights up to 35,000 lbs and tires up to 32″ in diameter. The system enables rapid leveling, with adjustable increments from 1/2″ to 6″ in under five minutes. In addition to levelers, the kit includes rubber mats and a carry bag for convenient transport and storage.
Focus areas include safety, compatibility with heavy travel trailers, and a faster, more precise leveling workflow. The anti-slip design aims to reduce movement during leveling, while the robust materials contribute to long-term durability in various camping environments.
Tri-Lynx Lynx Levelers

Tri-Lynx Lynx Levelers feature a modular interlocking design that supports high-load applications, with capacities up to 40,000 lbs. The 8″ x 5″ x 1.5″ blocks (interlocked height of 1″) come with a nylon storage bag and are made in the USA. They’re crafted to stabilize RVs, trailers, motorhomes, and vans, supporting appliances, water drainage, and a comfortable sleeping environment by ensuring even ground contact.
Essential considerations involve weight handling, interlocking stability, and domestic manufacturing. The design emphasizes durability, ease of use, and reliable performance across a range of RV types and ground conditions.
Camco 44510 RV Leveling Blocks

Camco 44510 blocks offer an interlocking nested design with a storage bag for organization. Each block measures 8.5″ x 8.5″ x 1″ (design may vary) and is part of a 10-pack. The nested design supports adjustable height and compatibility with multiple RV configurations, including single and dual wheels, hydraulic jacks, tongue jacks, stabilizer jacks, fifth wheels, and tandem axles. The UV-stabilized resin construction provides outdoor durability and resistance to weathering.
Considerations center on height increments, stacking ease, and universal compatibility with RV setups. The design prioritizes safety, portability, and practical storage for frequent campers.
Buying Guide: Key Purchase Considerations And Comparisons
- Weight capacity and suitability: Look for blocks rated to support the total weight of your RV, including tongue weight and wheel loads. Higher capacities are beneficial for larger campers and heavy-duty use.
- Interlocking design: Interlocking systems improve stability by preventing shifting during leveling. They also simplify stacking and storage, especially when full blocks are needed.
- Height adjustability: A range of increments (often 1″ or 0.5″-6″) allows you to dial in precise leveling on uneven ground, hills, or soft soils.
- Storage and portability: Carry handles, bags, and compact stacking features reduce hassle during transit and on-site setup.
- Material durability: UV-stabilized resin or high-density polymer blocks resist weathering and wear, extending lifespan in outdoor conditions.
- Ground compatibility: Consider terrain compatibility (grass, gravel, dirt, soft soil) and whether blocks have wider footprints to prevent sinking.
- Wheel compatibility: Ensure the blocks work with your RV’s wheel size and axle configuration (single vs. dual wheels).
- Setup speed: Some systems offer faster leveling workflows with integrated chocks or anti-slip features, saving setup time at the campground.
- Storage and organization: A storage bag or integrated carrying solution helps keep blocks ready for use and prevents misplacement at campsites.
When selecting, compare the number of blocks per kit, the maximum safe height, and whether the set includes accessories like chocks, mats, or bags. For frequent campers with varying sites, a modular interlocking design paired with a higher load rating generally provides the best balance of safety, convenience, and long-term reliability.
