The cover is easy to install and fits snugly even in WINDY conditions .As my tests showed, it can protect my RV from sun damage, bird droppings, tree sap, dust, and rainwater. The material is tough breathable, and does not scratch the paint. On the downside, it can be heavy and bulky to store, so make sure you have enough space for it. Overall, this cover is a great investment for any RV owner who wants to keep their vehicle in top condition!See full review
