AC in the heat
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...

Are you parked in the sun or in the shade? It really makes a huge difference.
During the winter, solar gain can boost the inside temps 20-30 degrees above outside temps if there is no wind. Same thing happens in the summer. You might only be seeing 10-15 degrees because too much of your rig is in direct sun.
This is on the money. We were in full sun last weekend. It was 91-92 outside. Best we could do with both ACs running was 77-78 degrees. I wondered if we had a problem and got the infrared thermometer and shot it in the AC vents. The temps at the vents were in the mid to upper 50s, or about 20 degrees cooler than at the intake. That means the ACs were working fine. It's really tough when you are in full sun with no shade to be found.
I bought my infrared thermometer at Auto Zone for about $25. It works great for checking AC, temps around the wheel bearings, etc. I highly recommend this to help you know if the ACs are working right. if the temps at the vents are about 18-20 degrees cooler than the ambient temp inside, the ACs are working fine. Good luck.
