We ordered ours from RVUpgrades
- one of the sponsors of this site.
That said, you might wanna check out this
previous discussion on rv covers & also check out my photos linked in that thread. Bldrbob is correct that cover movement from wind can rub. A cover should fit snug, but not too tight, so rubbing is minimalized. I shoulda ordered the next size smaller, since I didn't go custom, to get a better fit than the one I got. Lesson learned: we're, most likely, gonna build an rv port this summer.
