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.
My dash air can typically keep up with the two front seats, but in this heat lately through that big windshield I've had to kick on the gen and use the roof airs. I don't think roof air would do much for the cab without the cab air running with it.
I would like to say I run all 3 on the roof, but to date I've yet to get all 3 to work at the same time since we bought it a few months ago :)
