I'm sure this has been beat to death but, is it more efficient to run the dash air or to run the generator and one roof air.This is on a gas Ford v-10 and a 7000w Onan. Thanks for any input.
In warm weather, we ALWAYS start the generator and run the rooftop AC to cool the ENTIRE coach before we park for the day. It makes no sense to be uncomfortable after we have parked for the night waiting for the coach to cool off.
