We have a 2015 Thor Motor Home with two 13,500 Airxcel units. The covers are black. Most RV roof top A/C units seem to be white. My question is if black has anything to do with performance issues? ...
Never heard of the cover having anything to do with it. It sounds like something isn't working right. 85 is not that hot. If it's under warranty, I think you should bring it back. Our trailer has a 33' box with one 15000 unit and will freeze you out at 85.
