How to prevent RV condensation problems

I’m in RV sales and I hear from my customers about their problems with condensation in the campers and RVs. Here are some tips to help avoid condensation and control moisture in your RV:

1. When bathing, washing dishes, hair-drying, cooking and using appliances and non-vented gas burners, always turn on the nearest exhaust fan.
2. Keep the bathroom door closed and the vent open (if equipped, exhaust fan on) when bathing/showering. It also helps to keep the door close for a period of time after you have finished.
3. Do not hang wet clothes in the camper to dry.
4. In hot weather, start the air conditioner as soon as possible as it removes excess humidity from the air while lowering the temperature inside the camper.
5. If camping in the cold weather, try to manage the inside temperature. The higher inside temperature along with colder outside temperatures will cause condensation to form on areas that are not insulated as well as others such as canvas ends on hybrid campers, windows, vents and some wall studs.
6. Poor air circulation inside the camper or RV can cause condensation to form inside closets and cabinets. Leave doors partially opened to allow air to circulate inside closets and cabinets so the temperature inside the cabinet is the same as in the rest of the unit. Please keep in mind that a closed cabinet full of stored goods prevents circulation and can cause condensation.
7. The natural tendency would be to close the vehicle tightly during cold weather. This will actually compound the camco coverproblem. Simply put, you need to get the moisture in the air that is created from normal use outside. The most effective way is utilizing your vents and vent fans. My suggestion would be to have Camco covers put over your vents. This allows you to leave the vent open without the worry of water getting in. Also, if you cover your camper, make sure to use a “breathable” cover. This allows for air flow in and out of the cover to prevent mold and mildew.
8. Minimize the prolonged use of incandescent lights which produce heat and contribute to condensation in the roof above the ceiling lights. A lot of the new campers are coming with LED lights which burn cooler and won’t create condensation. If your camper still has incandescent bulbs, start to replace them with LED light as needed.

If the RV maintenance tips presented here are not effective in controlling your condensation problems, it may be necessary for you to invest in a dehumidifier. This will help to reduce the health risk to you or your family as well as prevent damage to your RV.
