Fixing delamination is a really big job. part of the problem is it is caused by water intrusion and you do not know the extent until the siding is off.
We had a 6 year old pace Arrow sided...thankfully the insurance footed the bill. 34'coach was $20,000 in 1997.
They have to remove all of the exterior attachments and pull the siding and luan backer board. On ours, there was extensive frame rust and interior damage to be repaired. Next they reattach a plywood to the frame and then the side has to go on as one big sheet with contact adhesive. Then all of the window have to be cut out and reinstalled as well as frig vent and water heaters and the roof edge trim. Then decals and any repainting.
Also had to replace about 1/2 of the interior paneling which meant cabinets had to be removed and rehung.
This coach was cosmetically in good shape except for the delamination. Looking back on it, we should have just walked away from it and had the insurance total it.
So expect a lot of work or repair the leaks and go on down the road.
