I have used an ADCO cover for the last 3 years. It is very easy to put on and take off, taking less than 20 minutes for either operation. We camp most every weekend and I put it on after every trip. It really helps keep the rig clean, and it is the next best thing to a garage for protection from the elements. Put something on any sharp edges and the cover should last quite a few years. I use 2 soccer balls for endcaps on my rear bumper and a tennis ball on a knob on the topper that sticks up when the slide out is pulled in.
