first time winterizing my new jayco x17z. Love it, but have to put it away already for the winter. I have read some different posts on winterizing and have read to just take the plug out of the hot water heater and put the valves in bypass mode before running the antifreeze through the lines. I was worried about water being trapped in the lines from the bypass valves to the tank so I cracked a bit letting the antifreeze do its thing but did not put enough in to see the antifreeze run out of the open tank plug because I've also read antifreeze and the heater element as well as the anode rod do not mix very well and could damage either. What do you folks do here?
