My fan runs constantly but that is standard for the unit. I am figuring out a way to put a 110 volt plug in thermostat near the breaker panel. The one I am looking at has a remote temperature control, I do not know how good it is but here is the link to it.

THE THERMOSTAT I SENT THE LINK TO WILL NOT WORK. IT IS ONLY 15 AMP AND MOST CAMPER AC'S ARE 20 AMP
