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...
Correct quote: We've got a 13.5k in our 16' TT... Last weekend, temps around 97f, mostly full sun. A/C will get it down to 75 in 15-20 minutes, and take it colder from there. Our TT doesn't have the best insulation, however it doesn't have all that much internal volume for a 13.5k A/C either.
Put six grandkids from 6-13 in there fanning the door and tell me how well it works. I was wanting a 4th last weekend.
