Keep the RV covered when it's not in use. The sun's UV rays can fade the RV's paint and damage its roof.
Wash the RV frequently using a mild soap. This will help preserve the vehicle's exterior finish, and the RV should always be washed following a long trip.
Have the RV's exterior waxed a couple times each year. Waxing can help protect the vehicle's paint job.
Regularly check for signs of water damage. Water damage can be easy to miss, and, if left unaddressed, it can lead to an expensive repair bill. Every few months, check the RV's roof, side walls, moldings, windows, doors, and vents for signs of water damage. A sealant can be used to make the necessary repairs.
Make sure the tires are inflated according to the manufacturer's recommendations. Under-inflated tires are more likely to suffer blowouts. Check your tires every month or so to make sure they're adequately inflated, and always check your tires before beginning a long journey.
Take care when turning. RVs are large vehicles, and it's easy to damage the exterior when making turns. Take long, wide turns, and use your rearview and side mirrors to guide you.
Use a spotter when parking. It's easy to scratch or scrape an RV when parking. Use a spotter to help make sure you don't damage the vehicle while parking.
Use an RV GPS device to avoid low bridges. Bridges with low clearance can damage the roof of your RV. An RV GPS device can help you avoid routes with bridges that are too low to allow clear passage.
