If you cannot build a fixed RV Barn or Port, a cover will protect the RV from sun, bird droppings, and similar exposure.
Our SoCal sun is too hot to forego cover, but covered storage is too expensive.
Adco is in the mid-price segment for covers along with brands like Expedition and others. Premium cover cost more and are much heavier but last longer being made from materials like Sunbrella. Discount covers fit poorly and do not have corner zippers to help install/removal.

Install is easy by one person - if you fold the cover during removal in a way that helps. We fold it up like a burrito then roll it into a bundle that is easy to move/drop/lift. That bundle is placed in the same location at install...keeps it simple and easy. We believe that is the key to owners who do or do not use a cover. It is simply the "7 P's" of performance.
Best luck
