My pole building isn't large enough for the motorhome to fit, so I decided to try a cover a few years ago. When we traded our old coach in last year it still looked new after 7 years. I was concerned about scratching, but they are pretty soft. I use Adco with Tyvek top and so far they've done the job. It takes me about 45 minutes to put it on by myself, They only last 3-4 years, so the cost is $100-$150/yr.
