When I was running the generator and rooftop A/C, the wife would set up a very quiet Vornado 120 volt fan in the living room floor, and blow that towards the drivers compartment. This provides much more airflow than a 12 volt fan, and is also fairly quiet.
I also found that the electric sun shade can reduce the heat in the drivers area to, and made driving more comfortable. I can adjust it slowly up or down to get the exact amount of shade I desire, or increase the amount of mountain views I can take in, very handy.
