My passenger side upper cabinets (over the couch) are coming off the ceiling at the face frame side. As far as I can tell, the outer portion of the cabinet frames are only screwed into the thin plywood backing behind the foam/vinyl ceiling facing, and the screws have stripped out of the plywood.

Has anyone found a better way to secure their cabinets? I asked Fleetwood/REV for a roof structure diagram in order to locate a structural member for mounting, but apparently, it’s a national secret, and unavailable to owners...I also removed one of my LED “puck” lights in an attempt to locate something substantial in the ceiling/roof structure, but I am reluctant to poke around in the closed cell styrofoam insulation that fills the area between the ceiling and roof. Additionally, I attempted to use a stud finder, but with the insulation, it isn’t reading anything helpful.

Fleetwood recommended taking it to a REV service center, but I have not had the best results with letting others “repair” this rig.

At this point, I am considering a more robust mount to the walls, and a trim strip to cover the gap at the face frame/ceiling (can’t get to the upper most corners because there is a square wooden chase with wires running along the upper corner/wall joint).

 Thanks in advance for any input/ideas
