Poor Cooling

Keep looking.

There is something goofy going on there. Heat strip. Outside air instead of inside makeup. Packing material not removed. Your temps of air seem normal.

Two units should do well enough. In 100 degrees maybe not so much.

We had a couple of fans to circulate air and when we were packing up yesterday to come home I turned them off. In no time the inside temperature went from 73 and 71 to 68 in both rooms. Someday I will get it figured out.

Last trip we had only 30amp service ... the spot was great shade but temps were mid 90's with heat index of 110 .... set the one A/C we could run at 73 and was cool as we needed ... even cold at night!! .... someone on here said set A/C on Low Cool because it gives air more time to pass over coils and creates less moisture ??

Make sure your A/C unit is clean. If there is dirt, grime, or other crud in the heat exchanger/cooling fins, then you quickly lose efficiency. So, pressure wash the unit on the roof when you get a chance and change out any dirty filters, if so equipped.

I was in Moab this year with a 26' trailer and a 13.5K BTU A/C unit. It was in the mid-90s there, zero tree cover, and too windy to leave an awning out unattended. When we'd get back to the trailer at 3-4 PM, it was still 92-96 outside and the surface of the trailer would burn your hand -- so, it was smoking hot in the sun. A/C unit kept is nice 68 inside with all shades drawn and windows closed.

But, our A/C unit is still pretty new and clean. I think that makes a difference.

I had an A/C unit in our PUP and it would only give me about -10 degrees from ambient. When the sun was out, it was basically worthless. I didn't think too much about it, because we didn't use the A/C much, anyway. When I sold it, I pressure washed it. I was shocked by how much dirt and crap came out of the A/C unit. River of mud. The new user probably has a much better experience with the A/C than I ever did!

The cooling issues for the bunk room seem to be common but what I struggle with the most is that the performance is so inconsistent.
