RV-ing in the winter is not impossible if you know what you should prepare. There are several things that you can do to keep the RV comfortable during winter. The first thing is skirting your RV. By skirting your RV, you can protect and keep the RV’s undercarriage, battery bays, and plumbing warm. If you don’t have a skirt installed, snow might pile up around the RV bays.

In addition to the skirt, you can also add extra protection for the vulnerable machinery in the RV, especially in the underbelly. Pipes, batteries, and plumbing usually need more than a skirt. To ensure safety, you’ll want to wrap them with heat tape. Moreover, you can also invest in a heated water hose or add insulation to your water hose to avoid frozen water line.

Many people also insulate their RV windows to maintain heat. Foam insulation boards, solar blankets, and bubble insulation are a few ways to do it. Furthermore, some people also use thermal curtains and RV sealant for extra warmth. They can maintain heat really well as long as there are no cracked or damaged stripping.

While all the previous ways are beneficial to keep warm, none of them can generate heat. To produce heat, you need a space heater, or in this case, RV heater. You can install inexpensive and energy-efficient space heaters to supplement your RV’s furnace. Without a doubt, investing in RV heaters are way better than replacing the plumbing after a freeze.
