I had already winterized the water lines. Drained water through the low point drain, then blew out as much water as I could get out of it. I believe the lines are fairly dry. Placed antifreeze into the water tanks(couldn't figure how to get it directly through the water pump. Turned each tap on until antifreeze came out. So I think I have that covered, however will recheck the hot water lines to be sure.
I have additional antifreeze to put into the waste holding tanks when I get the motor home to the storage area and will also put some down the trap. I did read about the macerator and would never have thought of that.
Thanks all for the help. Hope spring comes early this year.
