We are looking at a 30ft class C that only has a 13.5 BTU AC unit installed with 30 amps power cord. We are concerned that this set up will not be sufficient to get through these sweltering summe...
Our first MH was a 30 amp gasser. I don't know the size of the AC but it was not big enough to cool the rig. We added a second AC and had it wired where we could plug it into the pedestal separately. It also could be plugged into the regular onboard circuit. That way we could run either the front or rear AC via a selector switch. If you can afford to add the second unit you won't have to resort to a long list of things to do and still not be comfortable. Good luck with whatever you choose.
