Camco Fasten RV Leveling Blocks 10-Pack - Interlocking Stackable

Our review of the Camco FasTen RV Leveling Blocks finds them best suited for owners who want a simple, reusable way to level trailers and campers without improvising with wood. These ten bright yellow blocks deliver a customizable stackable solution with a patented interlocking grid and an integrated T-handle for easy carrying and compact storage. The single biggest reason to buy is the combination of predictable stacking geometry and convenient transport - the blocks lock together for storage and create a stable platform when used within the recommended stack height.

Key Features

• Interlocking Design: The FasTen grid lets blocks stack securely so users can build the exact height needed without slipping between layers.
• Universal Compatibility: These blocks work with single and dual wheels, hydraulic jacks, tongue jacks, stabilizers and tandem axles for broad use on most trailers.
• Quad-Grid Load Bearing: Each polymer block is engineered to support RV weight and provide a stable, non-compressing surface on varied ground types.
• Integrated T-Handle: The built-in handle makes the set easy to carry to the leveling site and twists down to secure the blocks for compact storage.
• Made in the USA: The patented design and domestic manufacture aim to ensure consistent quality and materials in each set.

Who It's For

These leveling blocks are ideal for full-time RVers, weekend campers, and small travel trailer owners who need a portable, non-damaging alternative to wood for routine leveling. People who prefer predictable stacking geometry and easy storage will appreciate the integrated handle and interlocking surfaces.

Those who use extremely tall stacks regularly or who expect the product to replace structural jacks under abnormal loads should look elsewhere or combine blocks with rated jacks; Camco recommends keeping stack height at 4 1/2 in or less for best results.

Pros & Cons

• Interlocking pattern and stackable design make height adjustments quick and predictable.
