? Heat & Air on Ford Chassis?

I live in Florida and our motor home is 37' long. During the summer, I definitely have to run at least one of the AC units with the generator. If it was just the wife and I, I might be able to get along with just the dash air but I wouldn't be comfortable. We travel with our dogs which ride in the middle of the motor home so they would be hot without running one of the AC units. Like others have said, it depends on the motor home and how you define "comfortable".
