A transient with just enough resources to own and live in a van with a mattress in the back. They can often be found in the parking lots of truck stops. They are recognized by their feet hanging out of the back of the van while they take a mid-day nap and the obvious fact that all of their worldly possessions are stuffed into the van leaving just enough room to sleep.
The other day I saw vansients at the Flying J. Their feet were tanning in the afternoon sun.
