? Heat & Air on Ford Chassis?

My only concern is the use of gasoline. In my experience, the dash air drops your mileage almost 1 mile per gallon. Using the generator and the house air is a lot more economical and cools the entire coach.

Strange, I have almost exactly the same coach as you, but a few years older.

I can’t even perceive the difference in mileage, in fact at an idle I can’t even see the drop in RPM when the compressor kicks in.

From what I can see the compressor takes ~3/4 hp under load, hardly an issue for a 6.8 liter V10 that’s already pushing a 35’ house that weighs some 20,000 pounds down the highway.
