Loose ceiling panels

[ourcastaway]

Hello, can't seem to find any info here. Some of the cabin ceiling panels in my 2000 340 Sundancer have pulled away from whatever keeps them attached to the overhead. The ceiling speaker and light area, just as you get to the bottom of the cabin stairs, can be moved up and down 3/4" or so. Where do I start ? I can't imagine this is that uncommon. Thanks for any info !

This is for a 380, but I would think they are similar

Thanks Chris, I appreciate it. Not the same obviously, but gives me a good idea of what's in front of me. I'm guessing the screws have pulled out from pounding......hopefully I can find a few of the pullouts and go back in with oversized screws. Thanks again.
