We left upstate NY yesterday with the temp at 6 deg F. A couple of days before leaving I fired up the heat in our coach, filled the fresh water tank and the fridge, and reloaded the freezable items we had stored in our cottage while out of the coach. Yesterday we loaded the last minute clean clothes and headed out. Today we're in southern PA, and it's 21 deg F outside and 72 inside. This afternoon we'll move to northern VA, and from there on down the temps will be above freezing and rising. We make a similar trip every winter...
