I opened the engine hatch today and discovered the insulation from the top of the engine compartment laying on top of the engine. It is a foam rubber like material which apparently was glued to the ceiling. The material itself appears to have degraded and separated from the glue.
Since we travel tomorrow, I temporarily reattached in the front with expanded metal, fender washers and sheet metal screws.
Anybody else have this problem and if so, how did you fix it?

Basil,
On the gas coach I had quite a few years ago, I insulated the dog house engine cover. I tried to glue and tape it in place, but found that it kept coming loose. On a visit to my brother-in-law's, who does custom car interiors, I used his glue gun to attach the insulation. This is a spray gun that sprays contact cement. The insulation held fine for as long as I had the coach. That said, If it were mine, I would find an upholstery shop and have them glue the insulation back into place. Then I would do like you mentioned, with the screws, for extra security.

3M makes a spray on contact cement (like spray paint). I believe one of the varieties is recommended for heat. I noticed mine is loose at one edge. I may be finding out soon, too.

Basil,
What took you so long? We had that happen a couple of years ago. Basically took three strips of angle iron and screwed it to the top with the insulation underneath it. Then for anything else that was hanging I took screws with big washers and tightened things up.
Ours started just before starting a trip. I think a lot of things wait until you are about to take off to break etc.
Lots of luck my friend,
Lyle

Mine is held in place (OEM) w/a 4" or so wide strip of flashing type sheet metal every coupla feet, with magnum size fender washers (~3" diameter) every 12-18" w/screws. Don't know if there is glue also.

Interesting, my 05 has the exact same setup as Emike's. Wonder why some of the units are different.

Probably 36', with bed over engine, vs 40' with floor over engine.

I always feel powerfully refreshed waking up w/400 horsepower under my bed.

Like Basil & Wayne, opened up engine hatch a couple of days ago and found ceiling insulation laying on top of engine. Read the various posts on this subject and elected to repair with spray adhesive, gutter guard runners, fender washers & hex hd self tapping screws.
