The hobie-cat sailboats are made of fiberglass laminated foam like this. It's super strong.

FWIW, when I build V2 of this thing, I'm going to do it out of 1x2 and 2x2 doug fir with 3/16" plywood panels outside, stained and sealed with epoxy resin, and with insulation affixed inside between the wood strips. Should take a fraction of the time to build and be able to get a similar overall shape.

What are your goals for your shell?
I plan to do some traveling and with only half ton pickup I'm limited to about 1800 pounds of load,,there are some comercial hard shell campers in that weight,but their square size and crappy construction turns me off,plus I can build it much cheaper..
I made my present camper (it's the pic in my avatar)from plywood 3/4 inch lower part and 1/4 inch walls and roof coated with Cold cure epoxy and marine enamel,,it's maybe 1000lbs empty,,not bad,but making it from Fglass&foam I could make it lighter still and round all the corners too ,to make it even more streamlined..

Theres ExpeditionPortal and RvNet sites for anyone interested in building RV related vehicles and things..
