Just a quick note about improving the efficiency of a propane fridge. Some years ago, I worked in Arizona and lived in a RV. The temps were 100F degrees plus,and when I came home after working in the hot sun all day, my ice cream was mush. A fellow worker showed me his set-up. He had installed a low drain 12V computer fan on his refrigerator vent and powered it with a cheap solar panel designed for maintaining batteries. It increased the air flow across the coils of the fridge which, in turn, increased the efficiency of the fridge. I tried it and it worked. My ice dream wasn’t frozen hard but, at least, I couldn’t pour it out of the box which was a definite improvement. I think more air flow would have improved it even more but I did not want to cut a hole in the floor to draw cooler air from under the RV.
