What is the make, model, and year of your motor home?
Where are you located?

ALL motor home manufacturers had issues from 2001-2007 with fiberglass delamination. The problem was from the main fiberglass supplier.
I have seen some of these repaired. A place in Mesa AZ was doing some delamination repairs last year.
A friend had a Newmar coach that was delaminating. He was the original owner and took it to the factory for repair.

One of the IRV2 members posted his repair procedures a few years ago. He was resourceful and parked the coach next to a brick wall building. He cut out the delaminated area, applied high grade epoxy and then used clamps between the brick wall and the coach wall to apply pressure to the wall while it was curing. He then had to fill the cut lines and repaint the area.

My suggestion is that you look down towards the bottom of this page
where there is a box labeled " similar threads "
You should find some informative reading there

Delamination is almost always caused by water intrusion into the area
so you should thinking about how that water is getting in

He has a Camelot and I had a similar problem with my Dynasty. Drilled a small hole at the bottom of the bubble to let the water out. Spent several hours trying to find where the water was getting in without success. Finally figured I was getting water when I ran the rear AC...drain line was plugged. Did not try and fix although I thought about drilling several holes at the top and putting wood floor repair liquid adhesive in and pressing the bubble back.
This post is my opinion, worth what you paid for it.

We had something similar to that on an 01 Ambassador, below the curb side bedroom window. I got a long drill up from in the wheel well into the bubble and drained it. Finding the leak was much harder. started at the window and eventually ended up at the roof AC in the bedroom. From vibration on the road, the bolts were all loose by at least 1/4" as the gasket had compressed, I tightened them and had no further problem after that, and the bubble was no longer noticeable after it dried out, which did take some time. Hope this may help, Happy Trails Bert

Delamination is the bubble. The filon skin has let go of its luan backing. The luan has gotten wet and the layers have separated.

You need to find and stop the leak.

Do a search here for delamination repair and you'll get lots of information. There are numerous techniques for the repair, none of which are easy, but all doable. I'm repairing serious delamination on a coach now. I am going to remove part of the side of the rig to reattach the filon to new substrate. You may be able to get away with an epoxy injection which is much less difficult.

Bubble in exterior wall

Thanks everyone for the help. Think I will look at the rear ac and see if leaking then drill couple of small holes in bubble and see if water comes out. Then go from there.
