Condensation occurs when there are high humidity levels in the air, combined with cold temperatures.  If you are RV camping in such an area, water droplets will often form on the walls, counter-tops and windows.  While “morning dew” (as it’s commonly called), is harmless outdoors, it can lead to a mold problem inside your RV and if ignored long enough, corrosion & wood rot.

Mold is not only unsightly, but can cause serious allergic reactions and respiratory problems.   If you see condensation, be sure to wipe it away as soon as possible.  Ultimately, you will want to take some precautions to ensure it doesn’t lead to more serious health and maintenance problems.  The following are some simple tips to reduce condensation inside your RV.

The first step is to reduce the controllable levels of humidity inside your RV.  When cooking, cover your pots and pans to reduce the water vapor, and be sure to hang any wet clothing outside to dry or take it to a laundromat dryer.  Be sure to crack the windows for a few minutes and properly ventilate your RV after showering.  This will clear the steam and even out the interior moisture content.

Second, running your thermostat a little warmer inside your RV will discourage condensation, which increases at lower temperatures.   The digital thermostats on the market today are programmable and make it easier to maintain the optimum temperature than in the past.   Humidity meters (or hygrometers) are also available online, or at RV retailers.  To prevent mold, it’s advisable to keep humidity levels between 30-50%.   You may also want to purchase a compact dehumidifier unit designed for RV camping.  Regular use of this appliance will immediately reduce the humidity without turning up the thermostat.

Lastly, there are do-it-yourself window insulator kits that provide a barrier between your window and humidity, reducing condensation.  These are available from RV supply, home improvement stores and online.  Utilizing these common-sense measures and investing in some of the devices available on today’s market will go a long way to reducing condensation inside your RV and its potential long-term effects on your budget and health!
