Cab of the truck works. Gets really old, really fast though. A small tent set up in back is far more comfortable.
If you know you are going to hunt a specific area a bigger tent with a comfy bed and Mr. Buddy heater is pretty nice. Especially if you get lucky and the wind doesn't blow.
But, as others have said, finding a used topper would be a priority. My advice would be an aluminum one of you intend to take it on and off. Fiberglass is annoyingly heavy.
