I needed info on winterizing my Cherokee 23DD and stumbled across this sight, (no manuals with unit and Forrest River had no useful info. Did it for the first time today. I drained all the drops and the tank and recapped them and drained the hot water heater. The cheap buggers only put one 3-way valve at the inlet of the hot water heater so if I would turned it the RV anti-freeze would have just went out the inlet of the hot water heater. So I took the outlet of the hot water heater off and plugged it. Then made up a suction hose to draw out of the RV anti-freeze jug. It took about 5 quarts, let it run a little longer to make sure the traps are full. Also took off the shower hose and drained it, and drained the water and RV anti-freeze out of the holding tanks. It took about an hour for the first time, now that I know what needs doing, should be a 30 minute job or less depending on how much water is in the tank.
With all the drop drains in these units I don't know how you would blow out all of the water, and get the water out of the pump. It's pretty easy and quick to winterize these with RV anti-freeze. I live where -20 to -30 below zero are the norm, so I need it done right.
