Hello all. We just took delivery on a brand new 2015 North Trail 33BKSS with a 15K BTU Airxcel AC unit. First time its been warm enough to really check the AC and it doesn't seem to be cooling. Its blowing 80 degree air. I think I can hear the compressor running, but it is not cooling at all. I'm guessing I'm going to have to take it back to the dealer for a service call, but I'd sure like to save myself a trip if its something simple. Any thoughts would be greatly appreciated.
