Opinion on winterability of my rig

Bukhrn: When I got my coach I was all excited about boondocking, lol...and now I can't really imagine why I'd want to do that, especially in the winter. So yes, I'll have power anywhere I stay. Good advice though on using the freshwater tank. I'm staying at a KOA in Staunton, VA this weekend and they have already warned me that the water fixtures aren't freeze proof. But they do have several that ARE and I can go there and refill if I need to. Doubt I'd want to move once I was setup, so I'll just fill my tank and be conservative about it plus bring a bunch of bottled water. I ordered the tank heaters and spent a couple hours this morning insulating the one exposed PVC pipe structure I have, hopefully that will suffice. I'll let you know, and thanks for the advice!
