I have a f150 with the little 5.5’ bed and run a soft topper, I will be sleeping a couple nights in that at an angle, if not in the back country with my little tent. I have a piece of 1” pink insulation foam cut to lay my pad on for extra insulation, I have a little catalyst propane heater and a hanging fan/led light combo unit. Battery powered boot dryer as well. It’ll all fit back there with my gear hanging and drying. Should be interesting in a week.
