I had a buddy that lived in a milk truck for 2 years. He insulated the walls and used to park in apartment block parking lots for power in the winters. He had a couch, TV, VCR, hot plate and a bar fridge. He showered at work. Ate at restaurants and washed his clothes at a laundromat. It started out because of necessity but he then started to save $$ to visit Australia. He went there, met a girl who's dad had bank and he's never been back.
