Make sure you leave a bit of antifreeze in the toilet bowl as well to keep the seal from drying out.
Geez, some of you are winterizing awfully early! The weather is just getting cool enough here to even begin to enjoy camping. We are just getting ready for our Georgia Mountain Fall Festival next month in Hiawassee. But I keep plenty of
af on hand. I blow out the lines and drain the hot water heater. I use the siphon hose to suck in through all the lines and then pour some down all the drains and leave some in the toilet bowl. So far never had any problems but we use our unit most of the winter. If it gets below freezing, I also turn on the furnace if we are sitting in the yard and have not winterized.
