High Humidity & RVs
Warm temperatures and high humidity are a recipe for disaster when it comes to RVs, travel trailers, and even vans.
Mold can start growing and before you know it you can have some serious problems forming even though you won’t be able to see it right away.

Mold can destroy your walls, ceiling, mattress, and even your subflooring. If it gets too bad you will have to rip all of it out and possibly do some major renovations to your RV or travel trailer.
The best way to avoid all of that is by keeping the humidity levels below 50% as often as you can.
An AC unit is basically a high powered dehumidifier that uses a compressor to lower the temperature inside the unit much more than a standard dehumidifier can.
An RV AC has the ability to gather a lot of condensation which in turn dries out the air really well.
If you have the electrical means to run your AC every day you may be wondering if you need to use a dehumidifier at all.
The answer is slightly more complicated than a solid yes or no.
Do I Need To Run A Dehumidifier When The RV AC Is Running?
I suggest using an indoor weather station in your RV that shows what the humidity level is inside (click here to see some great options for indoor/outdoor RV weather stations).
You can use it to monitor humidity and keep the levels of moisture in the air down.
If you are camping somewhere hot and moist like Florida you may need to run your AC and dehumidifier at the same time to keep the humidity levels in your RV at a safe level, which is 50% and below.
You also may get cold from running your AC constantly and need to run the dehumidifier as well.
When we camp near the ocean, it’s usually pretty hot and humid, so we are able to run the AC often to keep things dry, but we don’t like to run it at night.
We have a small RV dehumidifier set up that runs 24/7, it mostly helps with water collection at night and it pairs well with using the RV AC.
What it really boils down to is how humid of a climate you are in. In places that have low humidity, an AC will be enough to keep everything dry. But in areas that are hot and humid, you may need both.
At the end of the day, keeping your RV or travel trailer as dry as possible is going to save you a lot of money and heartache in the long run.
The effects humidity has on RVs it’s something everyone should be aware of, especially full-time RVers.
If you need to run both an RV AC and a dehumidifier at the same time to keep the humidity low, do it.
If you can control the humidity with the AC alone then that’s fine too.
It’s whatever works for you and the climate you are camping in.
What Else Should I Know?
The last thing to know is that you should close your windows and vents when running your AC.
It might seem like a good idea to keep the bathroom fan and a window open to circulate air, but you’re only making the AC less efficient by doing so.
The only fan we turn on when the AC is running is the stove fan since cooking adds additional moisture to the air.
