Winterizing where I live is pretty simple, drain water tank, holding tanks, drain water heater. Run pump to clear out. Pour pink into drains. Done.
But....my previous RV had to be returned to the factory in Indiana in December for total wall replacement under warranty. I found out to late it gets cold there. All my water facuets froze and busted including the one in the shower. Never knew it until we were sit up in Port A in March.
Now I do the blow out with air thing as well.
