Driving with the generator on

I'm from Florida, and most trips, most of the year involve using the air conditioner. I was told way back in 1995, when I bought my first Class C that it was more economical to use the generator to run the roof AC than it was to run the dash AC. I was told that a generator will use around .7 gal per hour. I almost always use the generator for air and not the dash air.

I don't know about your RV, but for ours, running the roof AC will not do jack for people riding in the cab. I know because when we bought our RV the cab AC was broken. We tried just using the roof AC (with generator) but I still sweated my butt off up front. We even bought a little fan to try and blow house air at the driver but it was still miserable up front.

Our Itasca is fine up front with the roof air running. Our Coachmen was fine when it had a 13,500 Btu Dometic followed by a 13,500 Btu Carrier, but it's not fine with its' current 15,000 Btu Advent AC. It must be due to the positioning of the forward vent on the Advent. The Itasca has ducted AC, while the Coachmen doesn't. My previous Class C was also fine with its' nonducted roof AC.
