Why Does My RV Have So Much Condensation?
Your RV has so much condensation because of an imbalance in temperature, moisture, or over-exposure to certain elements.
When warm air in your RV comes into contact with colder surfaces like windows, metal frames, or walls, the moisture in that air is released and small water droplets form.
RV condensation can develop quickly in cold weather. Water droplets will develop on the walls, along with any metal inside the RV too.
Condensation can actually damage the walls, floors, furniture, and cabinetry in your RV by causing mold to form, wood to rot, and metal to rust or become corroded.
Because it can cause so many problems, camper condensation is not something you want to mess around with. The best way to prevent condensation in RV is by removing the moisture from the air.

How Do I Keep The Humidity Down in My Camper in the Summer?
To keep humidity down in the summer, the most effective way is to run your RV AC units or a portable AC (Link to the best units below).
The air conditioner not only makes a room cooler but also removes humidity from the air. This is why you will see water running down the side of RVs when the AC is running. The air conditioner is pulling moisture out of the air in the RV and releasing it outside.
Run the RV AC with the fan speed set to auto, this will shut off your fan when the compressor shuts off on the AC and will prevent your fan from pulling outside humid air back into your RV. Using your air conditioner is great in the summertime.
