An RV accessory that is a must-have is a hygrometer. You can find it on Amazon.com. In order to keep your RV at its optimal humidity level, you should first determine what it is actually like inside it. Hygrometers and thermometers are inexpensive and can be used for this purpose. The relative humidity of your indoor space should be between 30% and 50%. You can try the following once you’ve determined that your humidity level is indeed an issue:
Let the air conditioner run.
Air conditioners remove moisture from indoor air when you leave RV windows open during summer in humid climates. There may be a solution to the problem alone if it is hot enough to require the use of the air conditioner.
Let some fresh air in.
A window or ceiling vent can help some of the humidity escape if the inside air is more humid than the outside air. The hot air rises, so a ceiling vent will provide the most air flow than a single window. While taking a shower, cooking over the stove, or releasing pressure from an Instant Pot, it is especially important to breathe through the nose.
Boost airflow.
By running a fan, condensation can be evaporated and your RV’s air temperature can be evenly distributed. Using a fan will allow humid air to escape more quickly if you have a window or vent open.
Dehumidify the room.
You can remove moisture from your indoor air with a dehumidifier if you do not want to also cool it. A dehumidifier is available in many sizes and prices, so choose one that fits the space you’ll be using it in. In addition, the higher the humidity level is, the larger the water container will hold; the more water it holds, the less often you’ll need to empty it. It might be possible to start with one and then add a second one if you don’t have room for one the size you need.
Invest in moisture absorbers.
Crystal moisture absorbers such as Damp Rid are great for boondocking and storing RVs when running an electric dehumidifier is not feasible.
Keep water vapour low.
You can try doing your laundry at a laundromat, using campground shower facilities, and cooking outdoors as much as possible if you’re still having problems. Showering, cooking indoors, and hanging clothes to dry all raise humidity and fog RV windows.
