We leave upstate NY for Florida after spending the holidays with our kids. We fill the water tank and refrigerator a couple of days before we leave, and just keep the two furnaces set at 50 deg.F until the morning we leave, running on an external cylinder that gets left behind. We've never had a problem with the hydraulic jacks sticking or the gear drive slide not working, and we've been quite comfortable in weather as low as -4 deg.F. We do watch the weather and change our travel plans to avoid snow or high winds, adding or subtracting a day here and there as needed until we reach warmer weather.
