I have been thinking about building a truck camper for a while, after looking it seems that a fiberglass composite construction would be a good choice for my plans. After reading about the Super Camper built by Tacodoc, using Niacore panels, I was really interested in going for a composite construction over wood or metal.This is going to be for a 3/4 ton long bed pickup, keeping the exterior walls within the truck's footprint instead of the wide campers offered in the commercial market.
What do you guys think about building a slide in style truck camper using fiberglass foam sandwich construction. The main structure would be assembled with 1.5" or 2" extruded foam panels then covered with glass mat on either side to create a monolithic sandwich structure. There some concerns over the structural integrity of the cab over part, there is really no way of adding strength without taking up interior space. The maximum weight in there would only be about 400-450lbs with two people, a foam mattress, and solar panels on the roof, personally I do not see a problem with the structure holding that weight but I am not a structural engineer either.
Let me know what you guys think and any comments, suggestions, or tips would be appreciated.
Here is a picture of the exterior, the interior layout is still being worked out.
