Camco RV Leveling Blocks FasTen XL 10-Pack — 10.5" x 10.5" x 1.5", Interlocking Heavy‑Duty Polymer

When you arrive at a campsite with slopes, soft ground, or gravel, a reliable leveling solution makes setup faster and safer. These FasTen XL blocks are purposely larger and stronger than standard 2x2 blocks, stacking to create a tailored foundation for single or dual wheels and a wide range of jacks. Built-in handling and a lock-down twist handle make transport and storage simple while the interlocking profile keeps stacks secure during use.

How do these blocks make leveling easier at uneven campsites?

The blocks are sized and shaped to form stable, repeatable stacks that bridge gaps and raise wheel or jack contact points. Their interlocking faces prevent lateral slipping so you can adjust height without rebuilding the entire stack. Because they're engineered for load bearing, a few stacked plates provide a sturdy base under wheels or jacks.

• 10-pack lets you build multiple stack heights for front-to-rear corrections
• Quad-grid internal structure increases strength under load
• Interlock pattern keeps stacks aligned and stable
• Works under single and dual wheels as well as various jacks

What sizes and weight-support details should I expect?

Each FasTen XL block measures roughly 10.5" x 10.5" with a 1.5" thickness, giving larger footprint and increased capacity versus standard 2x2 plates. The reinforced polymer design distributes weight across the grid to resist crushing and shifting. For safe practice, limit a single stack to a recommended height so the foundation stays reliable.

• Individual block dimension: about 10.5" x 10.5" x 1.5"
• Larger surface area supports tires and jack feet more evenly
• Engineered internal ribs improve strength and resilience
• Recommended maximum stack height: 4.5 inches or less

How do I carry, lock, and store these leveling plates?

A built-in T-style handle folds up for transport and folds down to lock a column of blocks into a compact bundle for storage. The twist-to-secure action keeps blocks from rattling in a storage compartment or trunk. That integrated design eliminates the need for separate straps or bags while making setup and teardown faster at the campsite.

• Integrated T-handle lifts for carrying multiple blocks at once
• Twist-and-lock action secures stacked blocks for storage
• No extra straps required — store as a single compact unit
• Durable polymer resists weather and repeated use

Are these compatible with different RVs and jack types?

Yes — the XL footprint and load-bearing construction make these blocks suitable under single tires, dual wheels, and a variety of jack feet including tongue, hydraulic, stabilizer, and fifth-wheel jacks. They are especially useful when mixed axle configurations or tandem axles require a consistent leveling platform. Always place blocks on solid ground and follow proper jacking and safety procedures.

• Works with single and double wheel setups
• Compatible with hydraulic, tongue, stabilizer, and fifth wheel jacks
• Good for gravel pads, dirt lots, and uneven campsite terrain
• Use recommended stack height to maintain safe support

Who is this for: Campers, RV owners, and trailer operators who need a dependable, portable way to level and stabilize their vehicles will find the Camco FasTen XL blocks useful. They suit people who want stronger, larger plates than standard 2x2 blocks, owners of heavier rigs or dual-wheel setups, and anyone who values quick setup, secure stacking, and easy storage while traveling.
