Why get a full time job/home/morgage (well maybe in 15 years when I'm bout 35 but no time soon) when you could just live in one of these and do whatever the hell you feel like wherever, whenever.
Looks like descent ones are running about $3-5K. Perfect size for overnights in resort parking lots, you can still fit into normal sized spaces. I plan on living in something like this at Whistler this season.
