Greetings Bug Zapper,
On my 2019 22M, I was missing one of the screws that hold the wall in place, but this wall is on the hinge-side of the bathroom door. My dealer did this in response to correcting a floor squeak. Perhaps the attachment at the top or the bottom of the catch-side of the wall is missing a screw?
Welcome to the forum.
P.S. If you would like to see some ideas for the 22M, my list is found by clicking <Eagle5> then <Statistics> and then <Find all threads started by Eagle5>
