They were made by 4Wheel Campers but are no longer made. The frames were aluminum and rumored to crack at the welds. Otherwise they're kinda sweet, I recently saw a REALLY nice one at Penrose in Colo on a '92-96 Bronco.
That's exactly what I want. I wonder how difficult it would be to fabricate one. It looks like the manufacture used a Bronco shell and attached it at the front of the camper shell to fit it right. It seems to just be a matter of finding a camper shell that fits the dimensions of the rig. It's definately worth looking into.
