Van living is sort of fun once you get used to it. Well, I guess technically I'm homeless since I just rent a room from my buddy who owns the house and I have a job , but in past years I camped in my van since it was much simpler than trying to pay the extreme rents around here. I did manage to get by pretty cheaply like that for awhile.
Eventually the trans started giving me fits, so I sold it but I may buy another in the future. There are entire forums about people who live this way, some are more extravagant than others.
