Use a closed loop cooling focus by using a heat sink to the outside, you already have a huge radiator outside: your camper skin. Use a very large finned plate attached to the skin on the inside, encase it on three sides, except top and bottom so it works as a thermo-syphon so you do not need a fan. Obviously place the fins top to bottom, not sideways. You will have to avoid insulation in that area. Fridge, heatsink.jpg
