Holy shyte Mark!!! Have you every been busy since I was on the board last!! I am totally diggin that camper shell.:drool: Looks like an idea I had to fit on a short box frame with the rear angle to gain some extra space. I guess I really need to go for a drive some weekend if you're going to be around and check that out. As always, your shop and abilities humbles my poor garage talent.
Camper is 8.5' at the base and 10' front wall to back wall, rear taper is completely consumed very usefully in the design. you could probably do something in the 7-7.5' range and a 8.5-9' wall to wall length on a short box without making it look like an afterthought and keeping the CG in check.
