No open RV Parks beyond Southern Ill. It really depends on how cold. Consistently below ero you could have some trouble. With heated coach and perhaps some 100 watt bulbs in wet bay areas would keep above freezing. Now to be save winterize. Yes bottled water and I use windshield washer for flushing. Much cheaper and works. Not knowing your plans for length of stay I can't advise but watch the weather. Keep slides in as much as possible. You will stay warmer and cover windows. You will eat propane.. I come from WI in mid-winter and often temps of zero and usually de-winterize around Nashville, U forgot that you will come up 65 from Nashville so north of Nashville not many open Parks.
