RVMATE 12 Pack RV Leveling Blocks
Best for: RVs and travel trailers that need stable leveling on uneven ground, especially when stacking blocks for variable heights. The set offers heavy-duty construction with interlocking design and two top covers to prevent tire contact with the block body.
Why selected: The 8.5″ x 8.5″ footprint provides solid stability, and the ability to stack blocks allows you to dial in precise leveling. The design reduces tire wear by limiting direct contact with the block body, helping to minimize movement.
Limitation: While strong, stacking height is finite; very steep slopes may require additional support or pads.
Tri-Lynx Lynx Levelers RV/Trailer 10 Pack
Best for: Those seeking the original interlocking levelers with a long-standing USA-made track record. Useful for general leveling, stability of appliances, and aiding water drainage.
Why selected: The modular interlocking design accommodates various leveling needs and supports up to substantial weights, making it a versatile choice for many RVs and motorhomes.
Limitation: Higher upfront cost relative to single-block options; relies on correct interlock alignment for best performance.
OX BLOX Heavy Duty Trailer Jack Blocks
Best for: Heavier travel trailers and fifth wheels needing robust support on various surfaces, including gravel and dirt. Stackable and designed to reduce wobble even when layered.
Why selected: High load rating per block (up to 10,000 lbs) and a patented stable design help keep rigs steady during leveling tasks.
Limitation: Heavier and bulkier than some compact options; storage and transport may require more space.
OULEME 12 Pack RV Leveling Blocks
Best for: Campers who want a complete leveling kit with a carry bag for easy transport and storage. The 12-pack provides a mix of interlocking blocks and top blocks for customized height.
Why selected: Interlocking design and carrying bag add convenience for setup and return travel. The blocks are built to resist UV aging and maintain density for long-term use.
Limitation: Interlock system requires proper alignment to avoid slippage during leveling; ensure top blocks seat correctly.
ROBLOCK 6”H Trailer Jack Block
Best for: RVs and travel trailers needing versatile support with a tall, stable block option for higher leveling needs. Good all-around compatibility with various jacks and stabilizers.
Why selected: High load capability and broad compatibility make it a solid option for different rig configurations and terrains.
Limitation: Some users may prefer a larger footprint for less substrate contact on very soft ground.
Buying Guide
What should you look for in RV leveling blocks?
Durability and material quality: Choose blocks made from high-density polymers or reinforced plastics to resist UV, oil, water, and temperature changes. Look for units designed to minimize tire wear and block deformation.
Load capacity: Compare per-block capacity and whether the system supports stacking. Heavier trailers require blocks rated for higher weights or interlocking designs that distribute load.
Interlocking vs. non-interlocking designs
Interlocking blocks offer strong lateral stability and easier alignment, while individual blocks can be more flexible for irregular spots. If you park on uneven terrain often, interlocking systems are usually advantageous.
Height range and stacking suitability
Check how much lift you can achieve with stacked blocks. Some sets provide 1.5″ top blocks and full-height blocks that enable multiple configurations for level parking on slopes.
Portability and storage considerations
Carrying bags, compact footprints, and weight affect how easy it is to transport blocks on trips. Kits that include a bag or case simplify storage in RV compartments or vehicle trunks.
Terrain compatibility
Consider whether you’ll be facing gravel, grass, dirt, or pavement. Look for anti-slip features and designs proven to stabilize on diverse surfaces, reducing wobble and movement.
FAQ
- What is the main purpose of RV leveling blocks? They provide a stable base to level a trailer on uneven ground and reduce movement while parked.
- Can I stack leveling blocks for extra height? Yes, many sets are designed to be stacked to achieve additional lift, but verify the maximum recommended height per model.
- Are interlocking blocks better than single blocks? Interlocking blocks generally offer greater stability and alignment, which helps prevent shifting on uneven surfaces.
- What should I consider when choosing for a heavy trailer? Look for blocks with high load ratings per block, durable materials, and a design that distributes weight evenly to prevent tire wear and block deformation.
- Do I need a carrying bag? A carrying bag helps with transport and storage, especially for kits with many pieces or tall blocks.
- Is there a risk using these on soft ground? On very soft ground, additional mats or ground protection can help prevent sinking and improve stability.
