If storage is your concern and impetus for pulling the small trailer, consider removing the entire back seat and seat belt box from the truck. We have a crew cab and by removing the back seat (6 bolts and 10 minutes) plus another 5 minutes for the seat belt box you have a huge cargo bay. I cut a piece of 1/4 inch plywood to form a flat floor in the rear raised area and we carry a ton of stuff back there .... 2 zero gravity chairs, 2 fold out chairs, 1 large folding table, 2 small tables (legs unscrew), a 10 x 10 expandable pop up, a Honda Eu2000i, a large camera bag (3 cameras & accessories), a large backpack for my Phantom 3 drone, a 24 pack of bottled water and 3 large "milk crate" type crates with typical camping gear (hose, electrical cords, adapters, tools, etc etc). Then on long trips we add another couple crates with dry goods for extended stays
Or you could check out a recent video showing us set up all this stuff (at about the 5:20 mark) ...
