Dutch, I haven't done ours yet, but everything was full of antifreeze when we got it, so I will give you a little info (all I know actually!)
The way I understand it, you should flip both valves on the panel for hot water heater bypass. Then pull the plug and drain it. Leave plug out. Then flip valve for easy winterizer. Hook up to antifreeze jug. Turn on pump, and start opening valves. Do both hot and cold side (will anything come when you select hot? Don't know) Do outside shower, inside shower , toilet, both sinks, low point drains, and lines going to bedroom for washing machine. For icemaker, I don't know. I took the hose off to flush antifreeze out, but we never used the icemaker, so I don't know. I know that line froze a few times when we were camping, but I would be worried about the water inside the fridge.
Sorry I wasn't much help, but this is our first trailer, and I won't be winterizing it till next week. Hopefully one of the more "experienced" fellows on here will chime in and give us some good info!Edited by: lenny
