Protect Your RV From Moisture Damage During Storage

Storing your RV properly when it's not in use is a vital component of protecting your investment. Moisture can be one of the major concerns during storage. This is because moisture can damage roofs, walls, and the interior. Leaks aren't the only concern – high relative humidity can lead to mold and mildew issues. The following tips can help you avoid moisture issues.

Tip #1: Protect the roof

The roof is the primary place where moisture leaks can occur. To guard against these, inspect the roof annually. If there is visible damage or peeling, then it is time to have the roof membrane replaced or resealed.

How you store is also important. An RV cover affords some protection, but it can lead to moisture issues due to trapped humidity. A better option is to park the RV under cover. This is simple enough if you have a large profile garage or carport. If you don't, then consider using an RV storage facility that has covered RV parking. If you must park in the open, use a loose cover that is open on the ends and do not park beneath trees.

Tip #2: Use your vents properly

Venting is important during storage to ensure moisture doesn't accumulate inside the RV. Most RVs have a combination of roof vents and side vents. The side vents are typically placed high on the walls. The side vents should be open but with the vent covers angled downward to minimize the chances of rainwater blowing in. Roof vents should only be left open if the RV is parked under cover.

Make sure the screening inside all open vents is in good condition. Otherwise, pests may make their way into the RV.

Tip #3: Dry everything before storage

Most RV owners know to drain the water and sewage tanks on their RV before storage. You can also have them blown out or you can fill them with winterizing chemicals, depending on your preferred storage method.

Another concern is other moisture trapped inside the RV. All surfaces should be dried before storing. This means after mopping and cleaning, you need to open the windows and allow everything to dry before closing up the RV for storage. Keep in mind soft furnishings and linens can hold moisture. When possible, store these in moisture-tight totes or bags. Finally, things like fridge doors and shower doors should be left open so no condensation is trapped inside during storage.

It's a good idea to check on your RV periodically during storage. If you catch a moisture problem early, you can usually clean it up and remedy the situation before it becomes time-consuming or expensive.
