So, what do you expect from your rig AC? We have a 13k BTU AC in the front/master and a 15k BTU in the living. At present, the main 15k AC is keeping the rig at 10-12 degrees lower than the outside...
Thanks so much for all the replies. It will be 94 here in DFW today so we have the rig set up and cooling out front. At the duct outlet with the longest run from the units, the air is coming out of there at 59, with 56 at the unit. I suspect the ducts will warm up as the day goes on with no overhead shade, but we are hoping this was more a condition of our surroundings and less about the unit.
