Too late to edit my first reply, so please ignore it and accept this one in its place:
We saw something very similar to that basic bus several years ago in ND or MT, I think. It appeared to be a long-term tour bus, with outside accessible showers, sleeping berths, and of course seating inside. They ate outside on folding tables, cooked outside,etc. We never got close enough to the group to ask questions, read signage or license plate to discover where they were from though.
Your bus conversion is outstanding! It is truly one of a kind.
