Used to have the same car while working security. Id often have to sleep in it between shifts, as it would be too expensive to drive home between shifts if I was far away. Id also sometimes have only 6 hours between shifts, making it make more sense to just crash in the car. I had an inverter tied to the battery, a small solar panel gorilla glued to the roof, and 3 car batteries in the trunk. A box fan in the passenger window, a 24 inch TV and a PlayStation would often come with me, too. Had a fucking kettle and a redi-set-go pizza cooker that was a beast for cooking just about anything. Effectively I would live in that car for several days out of the week, sitting in it during my shift playing PlayStation, and sleeping in it wherever I could find between shifts.
