looking for owners of 2004-2005 Pace Arrows

I'd be a little concerned about the water lines going to and coming from the water heater. At least on my '04 36B PA the lines are not in a heated compartment. If you look where your water heater bypass value is located, mine is accessed by the outside bay door just behind the right rear duals. Part of this area only has a thin piece of sheet metal between it and the outside. I would think one would need a small portable electric heater, a heat lamp, or some of that electric wrap around the lines.
