I did a lot of camping in a suburban. I used a popup screen enclosure and a couple of tables for a kitchen and slept in the truck. I used some surplus shelter halfs to create curtains. I attached a window screen to the magnetic weather strip from a freezer door and put that over a window for airflow. I had 2 smaller coolers and put those in the front seats/floor to keep critters out of my food. My bedding was a thermarest under some foam and blankets. Rolled up nicely.
