I think that basic concept (beta testing an interior) is underrated. We had a blast dreaming/tweaking/modding-again and camping all the while.

Yeah, I really think that this is the approach we will take. Last summer we rented a Dodge Caravan from escape campervans and explored the southern sierra for two weeks and absolutely loved it. It was a very basic (and small) setup...seats folded into bed in the middle, and had a sink, slide out stove, and fridge in the back hatch. Being able to wake up, cook breakfast, and continue down the road was great! We also did a few 2 night backpack trips, and the fridge was able to stay running and cold while not draining the battery. The only real downside to this van was the inability to stand up inside....also, a hot shower would have been nice (and toilet for the mrs.). That trip really got us interested in the idea to buy a van and convert to a camper.
I wish that there were reasonable rentals for larger camper vans (ie. roadtrek or sprinter) so that we can get a feel for the size/layout, but just can't seem to justify spending $500 a day for a rental. Heck a 2 week trip at this rate would be a nice downpayment on a van.
