Classic RV cover

I actually thought about inventing a three piece cover. Basically the center would just be a flat tarp with straps attached so you could use the straps to roll it up or roll it down while standing on the roof. Then the end pieces would be shaped like the end of the motorhome and would cover no more than about 10' of the end of the motorhome. They would come with long poles so two people could lift the end of the cover from the ground and use the poles to slide the covers over the front and rear. Then there would have to be some type of straps or a zipper to attach the end pieces to the center tarp. It probably would be hard to make it water tight, but it would keep the sun off and that's what does the most damage anyway.
