I had a kerosene fridge when I lived in the woods for 7 years - worked really well. Just light the wick and coolness follows - no worries about explosions or noxious gasses when I was gone fishing for days.
Camper / motor home fridges at least used to run off bottle gas, which amused me in the 1970s, because I remember that Plato (in one of the dialogues) had made an analogy, "just as you can't get cold from heat...".
