Ceiling fabric separation

[blazenpm]

I own a 2013 Forrest River "Georgetown" Class A RV. This RV has two roof A/C's. When the rear A/C is running, the fabric (possibly naugahyde) for lack of better description balloons down in front of the refrigerator area. My question: has anyone else ever experienced this phenomenen and what did you do to correct it?

Thanks for the good information. I will do a close inspection on the rear A/C system, hopefully finding and correcting the spot where the air is leaking into the roof liner.

For sagging headliner in my car I have used These pins,they may be helpful for the sagging part.The leak that was mentioned before would have to addressed also.

They come in many different styles and colors,if done correctly and spaced correctly they solved my problem and did look as if factory installed.

You have two problems; the a/c duct is leaking plus the backing of the fabric has rotted and failed. Make sure the screws holding the vents are actually securing them to the bottom of the ducts. You'll need to install a batten or two to hold up the fabric.
