RV Condensation: How to Reduce Moisture In Your RV This Winter

Winter is coming, and you’re noticing that moisture and condensation are starting to build up in your RV, making you worry about mold and dampness. I feel you! Moisture is no joke when it comes to RVs and campervans, so we need to do everything we can to keep em out of our little traveling slice of paradise.

Condensation on your RV walls, windows, and in your RV closets can build up anytime, but tends to be worse in winter because you are keeping the vents and windows closed for warmth, the weather tends to have higher humidity, and lower temperatures hold less moisture in the air, causing condensation. So we’re going to give you some tips to reduce the moisture in your RV over winter (or anytime).

Condensation Reducing Tips For Your RV

There are a few ways to effectively reduce the humidity in your RV.

1 – Use Dry Heat to Warm the Air and Reduce Humidity

Utilizing dry heat sources, like your furnace or an electric heater (if you’re hooked up to electricity), is a great way to dehumidify your trailer because it raises the temperature (warmer air can hold more moisture) and it doesn’t add moisture to the air, unlike open propane flame heaters like blue flame heaters. One of the best ways to do this is to use your onboard furnace to acquire this dry heat. Electric sources are another option for this process because they don’t produce humid heat like propane or blue flame heaters.

2 – Use a Portable Dehumidifier

A portable RV dehumidifier can be used to actually remove the water from the air, and there are plenty of options to choose from no matter how little electricity you have on hand.

If you want a zero-electricity option, you can use dehumidifying crystals – and these are great for your RV closets. If you want a low electricity option, you can use a small dehumidifier that doesn’t require a lot of energy. If you have a large fifth wheel or class A and you’re hooked up to electricity at an RV park, you can use a high volume dehumidifier to quickly get rid of your condensation woes. These are products made specifically for these vehicles and work efficiently.

3 – Vent the RV Regularly

Depending on the area that you are traveling in, temperatures may be mild. This doesn’t, however, mean that humidity will not be a problem. One of the easiest ways to prevent condensation is to vent the vehicle on a regular basis. Simply rolling down windows or allowing air to flow from sunroof components can roof vents can be helpful. This is an easy and budget-friendly approach to use.

 

There is no limit to the fun that families have year around with their RV’s. In fact, there are more and more people utilizing these traveling homes each year. According to the RV Industry Association, there were 39K shipments of these vehicles in August 2018 alone. Following these effective tips for maintaining RV’s during the winter months will help to maintain their comfort and reduce humidity.
