You want to first prepare your RV by finding good storage space. You may then want to consider investing in a good RV cover that can help prevent mold and mildew. Next, you will want to clean both your storage and RV to get rid of all the dirt and to keep pests away. Lastly, you want to shut down any appliances you have, empty out the tanks, and close all windows. This will keep your RV in great shape and ready for when you use it on your next road trip.
