I removed this tapered metal box, from a 2002 Chevrolet 1-ton school bus, that I converted into a "skoolie" RV.
It was mounted to the floor, inside the rear door. Apparently for tire chain storage. No reason it can't be used on a truck, buggy, trailer, boat, RV or piece of equipment. As a tool, equipment or ? Storage Box.
As mentioned, it's tapered from bottom to top.
At the bottom it measures 21" x 8" x 8".
At the top it measures 21-1/2" x 9" x 8".
The sliding lid measures 23" x 11".
$20.00 seems pretty cheap / good deal to me. If you agree and want it. Please give me a call at show contact info
