Sagging headliner

time2roll,

You are correct.

In my case with my motor home's interior, I would have needed to remove everything, furnishings and all because the material was throughout including the inside of the cabinetry. Then peel off the material, and then with a metal bristle brush, remove 100% of the foam, both crumbled and good, then attach brand new foam-backed head-liner material with a contact adhesive on both the foam and interior wall surfaces. It is the same process as restoring a headliner but on a much much bigger scale. Adding the complexity of so many different surfaces converging, there were finished seams to deal with. It would have been so much for anyone to deal with. That is one of a few reasons why we decided to sell the rig.

I also looked into a spray-on bed liner material, something much more durable but tan colored, not black. The cost of that option was tremendous.

I had an old s-10 pu that did similar. Need to remove the entire piece that it was adhered to. Then pull the fabric off the backing material. Remove any deteriorated material or foam between the fabric and backing material. Use spray-on contact adhesive and reapply the fabric to the backing. Very tedious and just one shot to make perfect. Although does not have to be perfect to look tons better and function perfectly. A bit of an art project.

Our 1984 Toyota Mirage had the "bed curtain" thing going on. It all came down during the course of one trip. The foam backing turned to dust and just let go all at once. We sold the rig like that. Fortunately there were cabinet and trim features that held most of it in acceptable condition, but not well enough in the cab-over area.

Here are a few pics I took for the sale ad.

As I said before on My Winnie I had the same problem,there is Lauan under the fabric and I first started with the Headliner Repair Caps they screwed into the Lauan and worked for a while. The problem was that the it started in a very small area but as time went on the foam and adhesive just started to come loose in larger areas. It is a stop gap that may work out for you if it doesn't get any larger.

If it does then you may have to do as I did and take it all down.

Good luck!

Thanks, everyone. I wrote Winnebago, too, and got this useful answer this morning: "We have seen instances like this where the headliner adhesion has let loose. Unfortunately, the only way to make a proper repair is to remove the old fabric and glue up new fabric or just replace the whole panel with the fabric already glued to luan paneling. This can be quite the task depending on how much fabric is coming loose from the panels. Depending on where and how much it is falling, you may be able to secure it using batt strips, upholstery tacks or rosettes. Those are just a couple of options that we have heard other owners doing."

This implies that there is something up there to which I can attach screws/tacks. Well, that'll be another fun project, unless I succumb and let an upholstery shop invade my wallet.

I agree. This was a common problem back then.
There were a few fixes that you can view on the Winnie owners forum. Gluing using 3M or stapling marine carpet in place after removing the old stuff were common fixes.
Being that its a tight area to work in I would try a professional auto upholstery shop .

I will also go along with this,it happened to my Winnie,the foam backing deteriorated and the fabric sagged. It had to all be removed,a very messy job. It was replaced with the carpet type that is now in most RVs

I would be concerned that you have a leak vs just age. I have had car headliners sag but usually ten years older than your rig. I would make some calls to auto upholstery outfits and discuss whether they fix sagging liners and have any experience with RV's.

Gotta peel it off and spray glue it back on. Better left to an auto upholstery shop.
