Mold spores need three things to grow: moisture, a food source, and the right temperature. That’s why it’s essential to keep the moisture levels down in your RV during the winter months – so you can avoid having a mold problem.

  • Fix any leaks and seal off any cracks. If your camper allows water in, you’re creating a breeding ground for mold. Use caulking and weatherstripping to seal off any potential leaking areas in your trailer.
  • Install a moisture barrier. If your RV is in storage for a few months, then you might want to invest in a temporary moisture barrier. You can install this on your walls or windows to keep the condensation down.
  • Place moisture-absorbent packs throughout your RV. These are handy, easy to place, and do a great job keeping moisture levels at a minimum. DampRid is probably the most common brand, but many are on the market.

  • Turn up the heat. By keeping the inside of your camper warm, the surfaces will heat up as well. This will prevent them from forming condensation on them. Avoid using your propane furnace and use the electric heater if you want to avoid moisture.
  • Invest in a dehumidifier. These come in various sizes, so you’d be sure to find one that works well in your RV. How they work is they draw in warm air and run it over refrigerated coils, which pulls the humidity from the air. They’re very effective and don’t cost much.
  • Push the moisture out. Use a vent with a fan to push the moisture out of your RV. The fan will remove water from your camper the same way your bathroom vent works. You can also open up windows throughout your trailer and turn on some fans to keep the humidity down.

These are just a few ways to keep the moisture out of your RV in the winter. It’s essential to use them because mold can be a severe health hazard and could damage your property if not taken care of quickly.
