My OEM cycles on and off. This one would probably run continuously. If the interior was comfortable the belly would have to be above freezing one would think.

I'm just throwing it out there to see if this is feasible. I sure don't know everything and all the questions are extremely beneficial. Online several say they have used this heater in their RV's and camper vans. It seems that this is the same type of heater that truckers use to keep their cab warm. We have many truckers on this forum so maybe they can chime in.
