I have a 2001 foretravel u320, Winterizing, is it coolant or water that that is passing through the heater cores is the basement and in the coach for heat? I have rv antifreeze pumped to my sinks shower hot and cold. If the coolant is coming out of the hot water side it is my understanding that the aqua hot is winterized is this correct. Thank you for your help.
