Camping in winter can be quite relaxing, but it also means combating the inconveniences of cold weather. Making sure your RV is properly insulated is one of the best ways to stay warm: Check the RV’s weather stripping around the doors and the windows’ seals and caulking. Windows should be covered with films and reflective foils. You can hang up heavy drapes to keep out drafts. Layer the floors with foam board flooring or rugs to keep the chill from penetrating through the vehicle’s underside. Place RV skirting around the base to keep chilly winds from freezing water tanks and causing other damage. You can also stay warm while you sleep in an RV by bundling up under a heavy comforter.
