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.
Leaving Julian, CA going to our home in Lake Elsinore, CA. the temp was 100 degrees plus. The dash A/C was unable to keep up so we got the generator going and turned on the coach A/C. Its so nice to travel in comfort.
