I haven't had this on one of my trucks since I was 17 or 18 years old. Had to move it to get to an International Pickup box trailer, so I figured I'd throw it on. It may not be streamline, but it has alot of room inside to load and put stuff. At first I put 2 C-clamps on and then took off Baja-ing down my road forgetting I had just put a canopy on the truck. When I looked back it was twisted half off the bedsides and hanging on by a clamp, but I saved it.
