We abuse our generator. We have it on along with the air conditioner especially when traveling, it beats the dash air. I think you would be very sorry if you didn't have a generator.
When we travel with my sister and her husband, plus their 5th wheel and want to stop somewhere for dinner or shopping her two dogs go in our motorhome with the air on. They don't have a generator in their 5th wheel and it gets very hot in there. When they travel by themselves they always eat at a fast food restaurant because of the dogs.
Another thing if you have a power outage at an RV Park you always have your generator as a backup.
