I'd call it a street lifestyle which is free. Anything you want (breakfast, lunch, dinner, shower) has to be paid for. The point of lifestyle is so that we don't have to count dollars spent on regular meals, and roleplay paying for electricity, water, sewer, etc. Lifestyle isn't just rent, but also represents money you spend on clothes, food, rolls of duct tape at the store etc.
When you park it to go to sleep, you have to worry about security, cops writing citations for camping in a non designated area (people do this now and its called stealth camping).
