While reviewing this post noticed I didn't mention two things found out later. When I disconnected the small water line under the oven going up to the ice maker didn't see much water drain out. Several days later decided to turn ice maker on and let it cycle in case more water was in the small line. Left the ice maker on for quite a while and when looked again, there was about three table spoons of water that came out. Also, the Keystone RV manual that came with the camper says to "not" run antifreeze thru ice maker. I agree that the ice maker water line exposed below the slide is something to remember if you are camping in cold weather and have not drained the water lines to the ice maker.
I also think will try to wait until all antifreeze is flushed from lines before opening the valve to the ice maker! Just more stuff to remember and to add to winterization check list and spring list.
