Seems to me someone should make a 12volt thermoelectric peltier style dog bed.
Peltier cooler are very energy inefficient.
Plus all they do is make one side of the device hot and the other side of the device about 30F cooler than ambient. What heat the cool side pulls out is expelled right back into the camper by the hot side. Overall you end up making it HOTTER inside the camper through the addition of the energy used to operate the device. You'd have to have a way to expel the heat out of the camper cabin in order to make it work, such as installing the device through the wall. I've never seen a peltier device that had the two sides mounted any distance from each other.
Cooling is one of those things that just doesn't translate efficiently to DC.
