Harbor Freight cargo carrier. I've added a wooden floor and enclosed the sides with wood. Everything is bolted and I used self locking nuts. It also has tail lights, turn signals and brake lights. Connects to the vehicle electrical system with a flat 4 connector. To buy a cargo carrier and modify it like this would cost well over the the 100.00 that I'm asking for it. I used it to go to AZ and back without any problems. The first one with cash takes it.
