... "vandwelling" is more a state of mind than a choice of vehicle. I know vandwellers living in everything from 40' motorhomes and converted refrigerator truck [great insulation there] all the way down to a Prius. We're a pretty diverse bunch, but the one trait that seems to exist in most everybody is the desire to live free...not free of cost, but free of constraints that seems to hold most sticks-n-bricks folks hostage, free to be in the next county [or state] by nightfall, or free to stay where we are for a while because it is a nice spot.
