So my new idea is to buy a cheap camper, gut the interior back to the bones (I find most of the campers have horrible interiors) and just refit it with what I really need. My question now is what sort of truck to buy.
How much room do you need? You might be better off building your own shell, particularly if you don't need to stand up in it. Something tall enough so you can sit up straight on the bed works pretty well IME. 1/2" ply and 1x2s, with a fiberglass exterior will work. If you don't like FG, canvas and Titebond is an easier alternative.
I'm going to guess that you could afford more than an $8k truck, but since it's a 2 year stay you don't want to spend a lot. And I'd rethink that. Get something reliable that will do what you want, and you'll be able to sell it easily enough when you are done.
