The main reason they are not on the rv's at the dealer is so they can sell you covers along with installation and get more money in their pockets. The same idea with slide toppers, dealer installed in most cases.

I just got done cleaning the roof vent covers from my rv and it was a chore. They seem to hold quite a bit of tree fallings and they eventually work their way into the opening and down to the screens. Are they necessary? I drove by the rv dealer today and the new rigs do not have them. Any thoughts?
