I did this for a while when I was working at Sun but it wasn't to avoid rent (I paid rent) it was to avoid my commute. When I was in full on work mode I viewed the commute as too much of a time drain (I lived in San Francisco, Sun was in Mountain View, 30 minutes without traffic, closer to an hour with. Each way. Blech.)
I had two VW vans parked next to each other, one was set up as a "bedroom", the other was set up as the "living room" and was also my daily driver. It worked pretty well if you don't count social life (I didn't have one).
