East Coast travel in February

We ran from Rochester NY to the south every Fall from 2002 to 2012 when I retired and did not have to wait for year end before getting out of town. Always turned on the heat and refrigerator a couple of days before departure and filled the FW tank as we were ready to roll. Did not dewinterize pipes until we needed them as we rolled. Usually our first overnight was in PA and we just ran everything. The only change we made from warm weather was we did not connect up water and sewer. We would drain black and gray before departure in the AM and stow the slinky. We were going where we had water day two in VA so did not bother about that. We then stayed at our son;s place in the VA mountains for a couple of weeks and often saw temps into the teens. Burned through a lot of propane but never froze anything. That was in an 04 Southwind and an 01 Damon before that. neither had heated tanks but the Southwind did have a furnace outlet in the wet bay. Kept a lit 100 watt light bulb for really cold nights.
