Living in the Northeast, I blowout and add antifreeze as part of my winterizing process. Better safe than sorry. However Keystone engineer must have had a bad weekend when he decided to put the pump access behind a panel in the front storage compartment. I guess if your flexible, then not a problem... I also leave my WH in bypass mode at put a sticky note in my camper to remind me (don't want ANY antifreeze getting in there).
