2008 Damon Daybreak 3276 Loose Mirror

I had the same on my 06 Daybreak. Except on the passenger side. I drilled all the way thru and used a nut / bolt set up. You can't see it from inside. It is just below the top of the dashboard. The out side has a bolt head vs a screw head so hardly noticeable.
They use wood type screws to set the mirrors and with the vibrating it just stripped the screw holes.
