Sources of Moisture
Moisture is everywhere, our planet is 70% water, you just can’t escape it. When it cools, moisture in the air quickly forms droplets of condensation, which can cause serious headaches for RV owners. There are several main culprits that introduce moisture into RVs, first any time you use your water heater you introduce plenty of steam into the air, whether you’re taking a hot shower or just washing up some dishes. The moisture you bring into your RV is the second major source, this can range from wet clothes and pets, to the glass of water you spill on the floor. Finally, the natural humidity of the location you’re travelling in can cause moisture buildup as well.
Preventing Moisture
There are lots of ways that moisture and condensation can get into your RV, but with a little common sense and some awareness you can cut it back to manageable levels. When you’re using your hot water, make sure to open a nearby window a bit to allow the steam to escape, if you have an overhead vent with a fan, that’s even better! When you do see condensation forming in your RV, have a small hand towel to wipe it up. This should also be a routine when you’re done showering, as the droplets left on the walls of your shower are a commonly forgotten source of moisture.
De-humidifiers
De-humidifiers are an awesome way to keep mold and mildew to a minimum in your trailer. These portable appliances remove moisture from the air and collect it in an easy to dump tank, keeping your RVs humidity at optimal levels. Lots of dehumidifiers are made to treat one residential room at a time, which can be enough coverage for a small camper or travel trailer, however if you own a Class A or a luxury fifth wheel you may want to consider getting two dehumidifiers for full coverage. One drawback to dehumidifiers is the need for power. If you’re putting your RV into storage having to check in and turn your dehumidifier on and off can be a pain, so you may want to look at a power free option.
Zero-Power Moisture Fighting
There are plenty of ways to zap moisture in your RV without plugging in to do it. One of the most common methods that people use is desiccant crystals. These products, usually known by their commercial names (such as ‘Damp Rid’) are designed to draw in moisture from the air where it’s condensed and captured. Especially for storage, you can place one or two containers in an out of the way place and check occasionally to replace the crystals.
