I also rewired rear fan that blows heat to drain valves so it would run even if furnace was not on.
Having a little fan up front might help too, which would direct warm air in to the pump/fresh water tank area.
The one at the back blows in to the tank valve area, so I'm sure by the time that air gets drawn through the tank area and up through the vent at the front of the camper, the air isn't doing much to keep the water lines thawed.
Just an idea....
