I just returned from a 8 day trip to Utah and Colorado and had the presence of mind (maybe?) to take a few shots of my setup in various stages of utility.
As it is loaded for a camping trip, purpose built pallet on the bottom, cooler, large Rubbermaid Action Packer with cooking gear, personal duffel and wife's duffel containing clothes and sundry behind that, 2 - 8 gal Rubbermaid Action packers behind that (not visible) containing tools, recovery gear, and dry / canned food. 2 sleeping bags, sheet, air mattress, and blanket are rolled into a tight bundle behind the cooler (top barely visible). Bungee net on the ceiling stows our clothes when we are sleeping.
In use for sleeping in the back. Rear seat bottoms are removed. Rear seat backs are folded forward. Front seats are slid forward. Rubbermaid 8 gallon APs are in the rear passenger footwells. Bedroll with air mattress / sheet / bags is in place and inflated. Personal duffels are on the front seats. Cooler and cook box are outside (cooler is bear resistant and I've never had a problem with animals; and cook box contains no food and the stove and pots are put away clean so there is no residue to attract animals).
Everything out but the pallet and the 8 gal APs.
