We always carry a ceramic cube as one of our heating options. We love camping in frigid weather, especially when XC skiing is available. Both PA and WVa keep a subset of their State Park electric campgrounds open year round (especially those near ski areas), so we have plenty of choices. Our van is capable of winter camping without hookups, but with shore power it is carefree.
