Would be nice to see what his actual camper situation is beyond that one shot of the passenger door. He seems to have all the seats (except the driver's of course) removed and a platform inside.
An even more interesting setup:
You'll see things like that around Bisbee AZ or most music festivals.
How about a boattail?
And a sleeping area in the boattail? (Looks overloaded with nothing in it to me.)
Still, I think I'd look for an Escort/Focus/Corolla/Accord wagon (or even a Toyota vanowagon or other 4 cyl minivan) and have a ton more room. I doubt he's moving that vehicle much.
However, maybe a tiny trailer is behind that ecomodder is the best decision?
