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.
For the sake of the environment I would love to burn less fuel. Given that argument I should travel in a Prius not a DP. My generator burns 1/2 gal per hour under moderate load and 1 gph under full load. If we are driving for 4 hours a day (not unusual for us) and running one roof AC on the gen I will burn through 2 gal of diesel for the privilege of keeping the house cool for when we stop. Worth it to me! Run the dash air too as the panorama windshield functions as a greenhouse.
