Camco FasTen Camper RV Leveling Blocks 10-Pack - Customizable

In this review of the Camco FasTen camper leveling blocks, the bottom line is simple: these stackable blocks are designed for RV owners who need a lightweight, adjustable way to level and stabilize trailers and truck campers. The single biggest reason to buy is the interlocking, quad-grid design combined with the integrated T-handle that makes carrying and storage easier than loose blocks. For those who tow or camp frequently and want a compact, USA-made option for quick leveling, this kit is a practical choice.

Key Features

• Interlocking design: The FasTen blocks stack and lock together for a customizable height so users can build precise support under single or tandem wheels.
• Integrated T-handle: The premium handle lifts to carry the blocks easily and twists down to lock them together for neat storage in a compact bundle.
• Quad-grid load bearing: Each 8.5 in by 8.5 in by 1 in block is engineered to distribute weight and provide stable support under jacks and wheels.
• Wide compatibility: Works with single wheels, double wheels, hydraulic and tongue jacks, stabilizer and fifth wheel jacks, and tandem axles for versatile use around the campsite.
• Made in the USA: The patented, durable polymer construction is manufactured domestically, offering reassurance on materials and build.

Who It's For

The Camco FasTen blocks suit RV owners, truck camper users, and weekend campers who need a portable, user-friendly leveling solution for varied terrain. They are especially helpful for people who prefer stacking blocks over constant use of jacks because they provide quick, repeatable height adjustments and easy transport with the handle.

Those who frequently demand extreme stacking beyond 4.5 in or need heavy-duty, non-polymer solutions for very high center-of-gravity rigs should consider heavier engineered pads or metal alternatives. Also, users expecting identical color across every unit should note that production changes may yield slight color variation.

Pros & Cons

Pros

• Lightweight and easy to carry using the integrated T-handle for one-person handling.

• Compatible with a broad range of jacks and wheel configurations for campsite versatility.

Cons

• Some users report mixed durability under extreme impact, so they may not suit every heavy-use scenario.
