I have 4 muffin fans that I run to keep the unit cool, 1 for cool air inlet, 1 that’s mounted to suck the fresh from the bottom to the top, and then 2 exhaust mounted fans. I seem to not have a temperature difference with the fans on or off.
After I got to my location I left the fans running for an additional 3 hours. Outside air temp was 75 degrees. After 3 hours I checked the fridge again and still was at that 55 degrees, so I figured I would let it sit over night and check in the morning. Still 55 and it stayed that way.
As for the altitude, last year I had my camper up to 10,500 feet at my hunting area and it never had a problem staying cool. This trip was at about 7,500 feet. I know altitude can mess with them but even at my house at 5,000 feet it still won’t cool below 55 on propane.
I was reading about the “roar” but maybe I’m wrong that you are suppose to hear that, definitely don’t want to blow up my camper and truck lol
