It turns out that both shower faucets were closed, so that's not the cause of my lukewarm water. Any other ideas? I leave for Sun Valley Idaho Thursday morning and it will be 15 degrees at night, so would like my hot water back. Also, does anyone know where I might find Winterizing specifically for an 2018 Elite I? I've attempted to follow the video for the Elite II, but am never confident I've got all the valves configured correctly. Got antifreeze to interior faucets and toilet, and a dribble to outside shower, but when I attempted to fill the Black Tank Flush line, it seemed to not go in. Much of the antifreeze squirted out where the hose connects to the Ollie. Thoughts?
