Keltrion 12 Pack (Grey) Interlocking Leveling Blocks
Best for: travelers who want a non-slip, interlocking base with a carrying bag for mobility. The kit includes 12 blocks and uses a similar interlocking system to other Keltrion options, with a gray color scheme for easy visibility.

Buying Guide: How To Choose The Right Camping Trailer Leveling Blocks
What stiffness and weight should I look for?
Choose blocks made of high-density polymer or reinforced materials that resist compression. Higher weight capacity supports heavier trailers and ensures blocks won’t deform under pressure.
How many blocks do I need?
Count the number of wheels on your trailer and assess site conditions. Interlocking designs let you stack to achieve the right height. A larger pack offers more flexibility for both single- and multi-axle setups.
Is interlocking essential?
Interlocking systems improve stability by preventing movement between blocks. They’re especially helpful on loose soil or uneven ground. If you camp on paved or firm surfaces, non-interlocking options may suffice, but interlocking still adds security.
What about storage and portability?
Look for carrying bags or integrated handles. A compact, stacked footprint helps with packing space in limited trailer storage. Ensure the blocks are easy to grab and carry from the storage area to the campsite.
What are height limits and safety tips?
Respect the manufacturer’s stacking limits. Avoid heights that reduce contact with the ground or cause wheel slippage. Use stabilizers in addition to leveling blocks on soft ground or on slopes to improve safety.
Which blocks are best for travel trailers vs. larger RVs?
For travel trailers with lighter weights, smaller packs with modest heights are often sufficient. For larger RVs, prioritize higher stacking options, stronger interlocking blocks, and higher load capacity to maintain stability across multiple wheels.
Maintenance and care tips
Inspect blocks for cracks or warping after heavy use. Clean to remove mud or debris that could affect stacking. Store in a dry place to prevent wear from prolonged exposure to sun and rain.
