6 Tips To Fix Battling Condensation In Your RV


Many factors contribute to condensation growth in your RV, from the ventilation system to the flooring materials you choose. When battling condensation in your RV, there are a few easy tips you can follow.

1. Check For A Clogged Exhaust Vent

Check For A Clogged Exhaust Vent

One of the first things to check is whether your ventilation system is properly functioning. If not, chances are you have a buildup of moisture inside the RV. This can lead to condensation.

That’s where you have water droplets on the exterior of your RV that are forming into the foggy air. The moisture can also come from a faulty seal on your roof or windows, which must address first.

2. Clean Out Your A/C

Clean Out Your A C

Next, ensure that nothing is blocking the airflow in and out of the ducts in your A/C unit. This includes cleaning out any debris or dirt buildup and anything that could tangle up in the fan blades or located behind them (like a leaf). Also, ensure all loose parts are secure so they don’t fall into the A/C unit and cause damage.

3. Tighten Loose Screws

Tighten Loose Screws

Another common culprit is loose or wiggly screws used to fasten parts together. These can loosen over time, allowing air to escape from your RV through the holes they create. So before you consider buying new features, look at those old ones just sitting around and see if you can tighten them up for better airflow and less condensation buildup.

4. Seal Leaks

Seal Leaks

If you haven’t already done so, make sure any gaps in your sealant are closed off properly with weather stripping or caulking material to prevent unwanted air from escaping into your RV through cracks and crevices (or worse yet, through the A/C).

5. Check Your Insulation

Check Your Insulation

If mold or mildew is growing inside your RV, it can cause moisture to condense on the insulation and drip down through the walls and ceiling. To prevent this from happening, ensure that your insulation is correctly sealed around all of the airtight seams.

6. Clean Fans

Clean Fans

Finally, clean out your fans as well. This means removing any dust, dirt, or moisture buildup that can cause condensation to form in the first place. If your lover is directly connected to your A/C unit, clean out both of them together – otherwise, you may end up with even more condensation building up over time.

Causes Of Condensation In An RV

Causes Of Condensation In An RV

One of the causes of condensation in an RV is the installation of an air conditioning unit. When the air conditioner is switched on, water vapor from the vehicle’s interior can condense on its surface, forming dew or frost. This dew can cause water leaks around windows and doors. However, dehumidifier usage can help to prevent this problem.

Another cause of condensation in an RV is poor ventilation inside the trailer. This causes moisture to accumulate inside, which may lead to molding and corrosion if not removed. To prevent condensation from forming on your RV’s exterior, keeping it cool and dry using awnings, shade, and proper ventilation is vital.

Install fans to move air around the trailer and increase ventilation so that moisture doesn’t build up inside. Last but not least, you should keep windows closed during cold weather to decrease the amount of water inside your trailer. Also, install a dehumidifier if you experience high humidity levels inside your RV.

If your RV is experiencing condensation problems, there are a few things you can do to correct the issue. First, make sure the insulation is installed correctly and in good condition. This can help prevent water from getting inside the RV and affecting its insulation, which can cause condensation buildup. Also, check the ventilation. Make sure there is adequate airflow in the RV.

This will help prevent water from forming on the inside of windows or doors, which can lead to mold and water damage. Finally, inspect all seals around the windows and doors to ensure they are adequately sealed.

If any of these steps aren’t followed carefully, condensation can cause problems for your RV’s interior. By following these tips and doing your best to keep your RV’s interior clean and dry, you can prevent condensation from becoming a problem in your camper trailer.

How To Prevent Condensation In An RV?

To prevent condensation in an RV, keeping the vehicle clean and dry is vital. Use a damp cloth to wipe down the outside of the RV and remove any dirt or dust. Also, ensure that windows are not fogged, and doors are not left open.

Additionally, use a dehumidifier when camping to remove moisture from the air. This can prevent condensation from forming and create a hygrometric environment inside the RV.

When camping in cold weather, configure your RV to have adequate airflow and heat circulation inside. To seal cracks and openings in your RV with insulation, use high-quality insulation that doesn’t lose its insulating properties over time.

Finally, a fan can help circulate air inside the RV, preventing condensation from forming on the windows or doors. These tips and practices can easily avoid condensation in your camper trailer or RV.

Ways To Dry Out An RV That Has Condensation

There are several ways you can dry out an RV that has condensation, including using a dehumidifier, a fan to circulate air, and a desiccant. One of the easiest ways to dry out your RV is by simply opening the windows and letting it air out.

Another way is to use a dehumidifier, a machine that humidifies the air in your RV. A fan can also circulate air in your RV and help it stay dry. Finally, a desiccant is another way to dehydrate your RV by absorbing moisture.

It can uses in emergency kits or stored in car trunks as an extra precaution. If these methods do not work, you may consider replacing the seals around windows, door frames, and vents so that water cannot enter the RV from these areas. You may also need to have the roof checked for leaks or replaced if it has been damaged by condensation (see Resources).


Certain factors can contribute to condensation in your RV. The humidity level outside and the temperature inside can impact it. Besides, moisture from vapor sources like water vapor or condensation can cause condensation.

If your RV is damp or the windows are foggy, here are some tips to help you fix battling condensation. Remember that moisture is something that cannot avoid.

It’s essential to keep your rig airtight and ventilated while camping to prevent condensation. By following these simple tips, you should be able to get your RV back up and running as efficiently as possible.
