Interesting observation on the 12 volt side of the compressor fridge as they miswired mine as well. That means the person who learned from that mistake did not share it with the new facility. I was told it was an easy fix.

As far as battery drain, I have not run it off the battery alone at all. I do not plan to do that when towing as I will do what others have posted instead. Cool down a day or two before on home AC power. Put frozen bottles of water in the fridge before going. I have read that will keep the fridge at about 40 degrees after 7 hours which is a good starting point at the campground.
