When we first got our 5er, I wanted them, now I'm not so sure. We are work camping in CO, came here straight from the Goshen Rally. The first week we got here, there was a bad hail storm & the end result was that we had to replace both vent covers as they were destroyed. A few days later I got to thinking about the awning, and extended it & there were 2 slits in it from the hail, and it was rolled up. I just wondered what it would have done to the toppers if we had any? Some of the campers were gone when the storm came & had their awnings out, and they were totally destroyed.
