Thanks all,
I just had it professionally cleaned so that isn't the issue, and I start it up in the morning but it doesn't keep up, even with the quick cool vents open. At night and in the shade it works fine.
I have used a laser thermometer on the unit. When I tested it, I had 72 degree air coming in and 60 degree air coming out. The air coming out should be closer to 48-50 degrees. This is also considering the +/- 5 degree factor of the thermometer.
What really concerned me was when I stuck my hand in the air return (above the filter) I had uneven temperature air inside. The right side was significantly cooler than the left. I shot the laser up to the top of inside of the unit and got a temp of 67 degrees on the top right corner of the shroud and 81 on the left. And here was the really wierd thing. The sun was on the right side of the coach but the LEFT side of the shroud was hot to the touch. The right was nice and cool. Also the "GL" wire seemed to be loose. Even tapping the wire would cause the unit to shut off. Doesany of this sound normal?
I find it hard to believe a 15k BTU AC can only manage to cool my coach 3 degrees in direct sunlight.
