It still baffles me why a lot of you put yourself through the winterizing BS. RV anti freeze is completely non toxic and can be completely flushed out of the system with a few fills and drains of the fresh water tank and lines.
Simply put 3-4 gallons of anti freeze in the tank and pump it through with the pump through every fixture until you see pink. Don't forget the outside shower/washer hook up/low point drains etc. I can do it in 15 min
