Don't forget about a Wildernest too. I picked mine up for $400. It wouldn't take too much effort to cut the front out of it, and devise a rubber boot between the camper and body interface. You might loose some structural integerity, but I am sure something can be done to reinforce it.
The lines are a little cleaner looking on the 'Nest too.
I have been thinking of removing the rear window and tail gate, and building a single door entry, like the one found on a Four Wheel Camper, to ease getting in an out of it.
