Winterizing is now history for me as I no longer winterize or de-winterize. I now have a heated garage to store my Class B.
However, in looking out two weeks in Minneapolis, MN I could safely say I could de-winterize because a few hours of overnight morning temperatures tomorrow are not going to do any damage. Does it get colder in in Ohio? I doubt it. And if you get on the road right away it would help more.
