Night time temps dipping to freezing this weekend so opted to winterize my unit today.
Followed the normal routine of blowing the lines out with air and follow up installing the antifreeze (PINK RV antifreeze).
Although never mentioned that I have read, also blew out the black water flush line to be assured any water in the line would not freeze and bust. Already replaced the backflow valve once when didn't blow out the line and it was in a tight spot .. not easy but doable and did not want to do it again.
All set for winter storage except for removing the battery.
