I plan on heading south the first week in January so I am not planning on winterizing my Class A Thor Windsport. I have my unit plugged in at home and I check the inside temperature on a daily basis. I have a small heater running inside to keep the coach temperature above freezing. I also have my furnace on set at 55 and the grey and black tanks are heated. I plan to put antifreeze in both the black and grey tanks as well. My question is about the location of the fresh water tank. Have I covered all the bases to keep from worrying about freezing pipes? Thanks.
