Have you got an RV in a storage unit? You need to keep the humidity under control to avoid it ruining your RV – So what can you do?
The easiest way to minimize humidity in your RV while it’s being stored is to choose a climate-controlled environment. These can be expensive, however, so you might also want to consider setting up a dehumidifier, especially during the damper months. Good ventilation and damp absorbers can make a difference too.

Let’s find out more about keeping your RV safe from humidity when it’s being stored.

A dehumidifier is one of the effective methods for keeping your RV dry if you aren’t storing it in a climate-controlled unit. You can use a dehumidifier to keep your RV dry whether it’s in your garage or in a storage unit.
Some dehumidifiers are battery powered, but most need mains power, so be aware of this and check whether you can hook one up. The dehumidifier will also need emptying from time to time, depending on how humid the environment is.
A dehumidifier does take power to run, which is an ongoing expense, but bear in mind that your RV will be suffering from constant damage if it is kept in a damp environment, and this could cost you more in the long term than running a dehumidifier.

Good ventilation is also critical to reducing condensation and humidity in the storage unit. It will be key to keeping your RV dry after it has been taken out of storage, too, so make sure you are running your air conditioning while driving it around for the first few days.
If you are keeping the RV in a garage, consider occasionally propping the door open (or a window if there is one) so that the area is ventilated and any dampness can evaporate. Moving air is great for drying things out.

If you don’t want to run a dehumidifier for hours or there’s no power outlet, you could consider putting some moisture absorbers in your RV before you store it. Put them in the dampest places, such as the shower, kitchen sink, and in closets or under windows.
Silica gel packs or bamboo charcoal will do the trick, pulling moisture out of the area and into the packet, rather than letting it sit on surfaces and soft furnishings.
The more of these you can spread throughout the RV, the drier it will stay, but bear in mind that they won’t last forever. You will have to remove them, dry them out, and replace them regularly, or they will cease to be effective.

You can also reduce internal moisture by preparing your RV well before you store it. That means draining tanks of fluid, deep cleaning the RV, and then drying the inside areas as thoroughly as you can.
You should remove all standing water and wipe down surfaces that are traditionally wet with extra care. The drier the RV is before you put it away, the fewer moisture issues you will have when it has been stored.
Taking a bit of time to condition any fabrics in the RV could also help. For example, you may want to wax or polish surfaces to increase their ability to repel moisture. Varnish areas that have worn, and generally do touch-ups to protect the inner parts of the RV.

Before you put your RV into storage for any long period, make sure you have considered how to minimize humidity and keep both the inside and outside of your RV as dry as possible.
