Should I Change the Waterline Antifreeze
My coach was winterized last November. We were not able to use the coach this past season due to medical issues but are planning to head south right after Christmas. Question is whether the waterline antifreeze is still good (I don't know how long it lasts). I always flush and sanitize on the way south (once the freeze danger is gone), so not worried on that aspect. Anyone know the lifespan of RV antifreeze or any other thoughts would be great. Thanks
