The generator is there and is to be used quite a lot so just use it and the gas consumption is about to 0.2 to 0.4 gallons per hour with the air conditioning on for a 4kw onan.

The Onan 4KW generator, gasoline-fueled, uses 0.3 gph with no load to 0.7 gph at full load, and about 0.5 gph at half load. While driving, you may find this extra fuel consumption acceptable. I am skeptical that is more fuel efficient than the cab AC.
