INSTEAD OF WINTERIZING MY 27 FT CLASS C THIS WINTER, I'M WONDERING IF MY OIL RADIATOR HEATER WOULD KEEP THE WATER LINES FROM FREEZING. IT GETS BELOW FREEZING A FEW TIMES IN THE WINTER
If you replace the return air grill for the furnace with a dual window fan and place the oil heater right in front of that it may keep the water lines from freezing.
