I did have to replace the pump control 3 times as they keep failing, so the last time I modified it with a separate relay for the pump and it has worked perfectly since.
Watch the duty cycle on the pump so it doesn't overheat.
We thoroughly enjoy our 3920 and can't wait for the snow to clear so we can again get on the road!
I also carry a small gas can with just in case we need to take fuel from the aux. and put it in the coach.
Vet, you mentioned a separate gas can to transfer fuel from the aux. tank to the coach tank. Can't you transfer fuel directly from the aux. to the main using the fueling station pump, hose and nozzle? The main tank is within reach of the fueling station nozzle right? I'm just curious because that was one of my thoughts if I end up filling the aux. tank . . . using it to occasionally add to the main tank.
