We just camped at Lake Theodore Roosevelt, AZ last weekend. It was the hottest weekend on record with onshore temps as high as 115*F. Completely dry camping running the generator 24/7. The Norcold 4 door refer was running when we left home and was packed with already cold food. The refer is in a slide and the refer side was facing south. The temps when we left home on Friday noon was 36* and 4*. When we left the lake at Monday noon, the temps were 48* and 32*. I switched to propane for a day and it didn't seem to make any difference. Part of my problem is grandkids and wife who like to open the doors and look and not even take anything. I'd switch to a home refer but am unable to find one that will fit the opening.
I was thinking of hanging clear plastic sheets over the openings, attached at the top so the "lookers" can still see when they open the door but it will still retain some of the cold air.
I believe mine is properly installed with baffles and multiple fans.
