Your RV’s exterior will be the most exposed portion and, therefore, the most prone to damage. RV exteriors face debris, wind, snow, rain, ice, and other perils of winter head-on! Your camper is going to be very cold. The least we could do as RV owners is put a blanket over it, tucking it nicely for the winter. The equivalent of a blanket for RVs is a nice, durable, weather-resistant cover with zippers for easy entry and enclosure.
