Hi Charlie! That's unhappy news about your C. This forum is populated with owners of molded-fiberglass trailers, so we are not experienced with delamination. However, I also belong to the Good Sam/RV Net forum and have read some of the horror stories over there. A very few folks have tried re-gluing the sandwiched layers (applying pressure) if the underlying wood was not damaged by water intrusion. But I think the most common solutions tend to be (a) replacing the delaminated section, which is expensive or (b) trying to sell the unit to some poor shmuck who doesn't recognize the problem! I hope you won't be tempted to try 'plan b'.
