Just make sure you disconnect your water hose at night and drain it. I camped last year in Herkimer NY last day the KOA was open and my hose froze, but camper was fine. An hour in the sun defrosted the hose and I cleared it by running water through it. That was in my 21.5 Antigua Hybrid. Would also HIGHLY recommend some liners for your tent ends. I made it through that horrible New England blizzard in Mass with 22" of heart attack snow. 26 degrees both there and in Herkimer. No freezeups. If you have electric, buy a small electric heater. One with auto shut off if it tips over. I have a Sunbeam that's good. Switchable between 750 and 1500 Watts.
