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...
We have a small Class C that can usually be kept cool throughout using either the cab air conditioner or the coach's 13.5K roof air conditioner.
However, once when we parked to rockhound in the Texas Panhandle in August we had to idle the V10 and fire up the generator in order to use BOTH the cab air conditioner and roof air conditioner in order to keep from heat-stroking while we ate lunch!!
