Here is a twist to this same question...
We have our first residential fridge in our fifth wheel and are weekend warriors..
Generally we may have 2-3 weeks between camping trips early on, the temp outside can get up there, which of course makes the temp inside the trailer 95-99 degrees.
I have been concerned about the fridge running for 2-3 weeks while stuck inside a giant heater??
So what we do is shut it down when we get home, and turn it back on 1 few days before our next trip. . .
