I would be concerned with the freezer holding at 20 degrees as well as the fridge temp nearing 50 degrees. This unit is running at a good 10-15 above normal range of food safety.
Do you switch it over from electric to propane or is it set on "auto"? Do you have any problem lighting the stove or oven? Do you have a thermometer in both the fridge & freezer?
Either way this would be on my list for the service department to fix. Your food items are in the danger zone at the temps you listed.
Great choice for "Living within my means" and camping for one...
