Eighteen inches of powder-coated steel in the shape of a five-gallon fuel can, X-braced sides and all — except this one opens. The hinged front door reveals two pull-out drawers, a lift-out tray and a row of screwdriver slots down the inside of the door, everything sitting on non-slip liners. It bolts into a standard jerry can mount, so it rides on the back of the truck exactly where fuel would.
