water damage advice

[FCMINCOFFROADDI]

I have a 06 Thor Transport toyhauler, I guess over the winter the window in the garage area leaked and the wall is soft. I tore out from the inside, should be able to fix it, but it looks like the plywood had been glued to the skin? Anybody attempt to fix something like this? From the inside there is wood panel then app 2" of foam insulation, then appears another wood panel on the exterior glued to the skin. Any help I would welcome..

Not that replies would differ - but (FYI) there is a Toy Hauler Forum (here).

Is the skin separating from the plywood (de-laminating). If not you may be OK in just making sure the plywood is dry. And glue another piece of plywood to it for structural strength if the outer plywood is also soft.

If it does de-laminate you can fix it from the outside. Look on YouTube for videos.
