I don't fall into the school that covers will scratch and ruin the paint. I used a cover for 2 years (that's about all they last - if that long) and it kept the MH very clean and shiny. But after wrestling with it I decided it was just too difficult to take it on and off and I am in fairly good shape. Aside from the difficulty , ask yourself what do you do with the cover if you take it off? What about when the cover is wet? I had a lot of trouble not only getting it off in the snow but storing the cover was problematic. Any moisture will start mold on the cover and then you debate putting it back on. Covers have their benefits but I think most will say they are a royal PITA to deal with. It's a whole lot easier to wax the MH and care for your roof and about the same cost as a cover if not less. If you can't do it, pay someone a few hundred bucks a year to wax it for you.
