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.
One thing to consider is the maintenance costs for the generator, not just the fuel consumption. However, just be comfortable whatever it takes. If you have to pinch pennies that much, you can't afford a motorhome- period!
