I'm trying to figure out what is so difficult about this.
You were basically forced to sleep in the Van, and only for 6/7 days a week. Since you were allowed to leave, why the hell would you bother with all the porta-potty/food prep garbage?
Should have been forced to STAY in the van 24h/day for 6/7 days a week. That would be living in a van.
how much did you actually profit from the 9k after all van-related costs or anything extra that you had to buy, that you wouldn't need if you were living in an apt.
