AUTOSAVER88 36 in Underbody Tool Box - Heavy Duty Waterproof Storage

In this review of the AUTOSAVER88 36 in Underbody Tool Box, the bottom line is simple: this is a practical, weather-resistant storage chest for truck, trailer, and RV owners who need organized tool access without adding excessive weight. The standout reason to buy is the combination of a high-density aluminum build with sealing strips and a lock, which keeps tools dry and secure while offering foldable T-handles that reduce snag risk during driving. The review focuses on fit, durability, and real-world usability rather than marketing claims.

Key Features

• Drop-Resistant Storage: The included anti-drop net helps keep small tools and supplies from shifting and falling out when the box is opened, improving organization.
• High-Density Aluminum Construction: Sturdy aluminum with a non-slip diamond plate surface resists oxidation so the box maintains strength and appearance in tough conditions.
• Secure & Smooth Access: A strong lock with two keys and foldable T-shaped handles provide reliable security and easier operation while reducing obstruction during transit.
• Weather-Ready Use: Sealing strips and a professional powder coat help keep water and rust out so tools remain dry and protected.
• Flexible Installation Options: At 36 x 17 x 17 in, this underbody box fits a wide range of trucks, trailers, RVs, and workshop applications for versatile storage placement.

Who It's For

The AUTOSAVER88 36 in Underbody Tool Box is best suited to DIYers, contractors, and tradespeople who need a lightweight, corrosion-resistant storage chest mounted under a vehicle or in a trailer. It is also a good fit for RV owners who want to free up interior space while keeping basic tools and supplies protected from the elements.

Those who require heavy industrial security or an all-steel, ultra-rigid construction for very heavy tools should look elsewhere; while customers report good overall quality, feedback on build solidity is mixed and some users describe lighter panels compared with heavier steel alternatives.
