In reply to BC:
I have a mercedes sprinter, high top, medium wheel base, and live in it full time. High enough to stand in, small enough to fit in normal parking spaces compared to the long wheel base and also has everything inside that I need, bathroom, kitchen, bedroom.
I spent a month in a mazda bongo a few years ago, and the anger monkeys were certainly running around due to lack of space. Although for weekend trips it was fine.
