How do I keep moisture out of my RV in the winter?
As someone who has spent many winters living in an RV, I can tell you that keeping moisture out is crucial for both your comfort and the health of your RV. Here are some tips that have worked for me:

  • Open a vent: As mentioned in the input, opening a vent can help keep moisture out. The cold air outside is usually more humid than inside air, and your RV propane furnace (if vented) is able to blow warm, dry air. This can help circulate the air and prevent moisture buildup.
  • Moisture Grabbers: These hanging water absorbers are ideal for small closets and areas. They work by absorbing excess moisture in the air and trapping it in a container. You can find them at most hardware or home goods stores.
  • Powered Dehumidifier: If you have a larger RV or are dealing with a lot of moisture, a powered dehumidifier may be necessary. These machines work by pulling moisture out of the air and collecting it in a container. They can be a bit pricey, but they are worth the investment if you plan on spending a lot of time in your RV during the winter.
  • Keep windows and doors closed: This may seem obvious, but it’s important to keep windows and doors closed as much as possible to prevent moisture from entering your RV. If you need to open a window for ventilation, make sure to do so during the warmest part of the day when the air is driest.
  • Use moisture-resistant materials: When outfitting your RV for winter living, make sure to use moisture-resistant materials whenever possible. This includes things like moisture-resistant flooring, curtains, and bedding. These materials will help prevent moisture buildup and make it easier to keep your RV dry.

By following these tips, you can help keep moisture out of your RV during the winter months. This will not only make your living space more comfortable, but it will also help prevent damage to your RV from mold and mildew.
