The power sun visor shade on the passenger side of my 2005 Itasca Horizon broke loose from it's mounting and fell. This shade is held on by 4 very small machine screws I estimate # 4s
. First one side broke making it hang sideways, which in turn sheered the other 2. To fix it I just drilled out the brackets and used self tapping sheet metal srews. Take a look at yours and make sure they are tight so you don't get a lap full. Probably saved 3 cents by not going bigger.
