Could be an awesome project, but you'll need some serious tools and some real fab/construction skills to not make a rolling gypsy mobile that looks like something out of a movie.
Check out a couple threads on here for some ideas. A guy up here made a 2 pod camper on a flatbed. Super sweet ingenious setup, but the time money and skill that went into it was considerable to say the least.
I'd save the construction projects for making money and buy a camper to slap on a truck and get to living the life! Unless you could do something like graft a small class C camper onto a F550 or some big dually.
The big issue will be weight, the provan you're looking at is super light. Like a pop up TC or less. To make a sturdy, full feature, well constructed camper will be pretty heavy I think and without engineering ability for wood or at least common sense fab skills with aluminum or steel frames, it will be tough to build something "bulletproof."
That said, still sounds like fun. Weigh the practicality though.
