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...
Well can't be too disappointed with out OEM Dometic 15K BTU on our 2005 Copper Canyon, we sit in full sun and at 98 outside we were at 80. We are looking at a second 13.5K unit for the bedroom.
