I finally tackled the sagging ceiling . I decided not to open it up totally because of the mess of dried up glue, disintegrated foam, rust etc. I took down the vinyl strip and replaced it with a finished piece of pine. I also found some buttons that matched the originals perfectly. Buttons come with a satisfactory screw for installation. Thus the tuck and roll look. (link below) This Minwax stain was a good match also. Anchored wood to ceiling with 1/12" self tapping metal screws. It should last as long as the coach. ^.^d
All in all, a pretty clean fix.

Good match
