Ceiling sag

[Yesirv2]

I have a 1995 Hr 5er and the ceiling is sagging in places,It seems to be vinyl with strips every so often Are they glued up? Is there framing under those strips I could screw into?

Thanks

Had a 95Alumalite that we ordered from factory. Had the same problem. Found that the strips are pressure fit. You can take a short 2 x 4 and a 4lb ham mer and tap the strips back up, but when it gets really hot--down they come. Have owned 3 dif makes of 5th wheels and the Holiday Rambler was a real dud!!!!!!! If i were trying screws , I would use sheet metal as the cross members is aluminum. GOOD LUCK
