Controlling relative humidity
Controlling relative humidity in a RV is important to minimize risk and damage due to moisture. Ideally, the relative humidity should be 60% or less. Humidity can be controlled using a “humidity sensor”, which is a small device that measures temperature and relative humidity. To maintain the humidity at 60% and less in your trailer, you can use a fan, air conditioning or a portable dehumidifier. In a cold climate, relative humidity requires a rate less than 35% to avoid condensation problems.
If the RV is used mostly in a hot and humid climate, it may be difficult to maintain relative humidity below 60%. A dehumidifier will help, but it is important to check that water condensation is directly discharged through a drain.
