It's hard to really see everything in the picture, but the hot / cold low point drains are on the far left. Wish they'd have put valves, but they just got caps under the MH. May add that later. As for winterizing, never done it in the 10+ years we've been RVing. It's either in the enclosed shop, or being used year round. We're not seasonal campers. Hot, cold, don't matter, we're going. Just gotta use precautionary measures in the extreme cold. Usually run off water tank and fill once a day then. Got a temp sensor by the water filter area, and with the ducted heat, its never got below mid 40's.

At least in Heaven, RVs will be perfect, and I won't have to keep fixing them.
