Look, I had a small generator in my Leisure Travel Van. It had only 30 hours on it and kept overheating. We figured it out. We had driven down a very dusty dirt road. The road kicked up fine powder. Even though my generator was not running, the powder got into the air intake of the generator. Once we reached a cummins dealer in Elko Nevada, they performed the service. The mechanic came into the waiting room and showed us the air filter which was throwing off all kinds of this fine powdery dirt. There was no question that was the problem. I think If I did this again, I would cover the air intake when going down dirt roads or make some sort of fitting that I could put on or take off.
