The bathroom wall behind the dinette is about 3/16" plywood, glued on each side to wood separators between that wall and the bathroom interior wall. Only the glue joint secures this wall for at least several feet above the top of the dinette seat back.
On this wall is mounted an AC outlet, quite a distance from the glued edge. When pulling a plug out of the outlet, the wall flexes quite a bit. The glue joint finally parted company and the wall is now very loose.
I made a temporary fix by moving the thermostat closer to the edge of the wall so that I could put two countersunk screws where they are hidden by the thermostat base.
Tuesday, when I bring the A/S home to prepare for a trip, I will get the interior warm, remove the added screws, squeeze some new glue into the joint, and reinstall the screws. Hopefully, with some care in removing plugs in the future, this will keep the wall intact.
