Sounds like you have a good plan, the only thing I would add is if you use epoxy resin make sure the area is dry first. Acetone will help the drying process. It is a solvent and will flash off quickly removing the moisture. The second think I would add is when I did mine and it was a much larger area than yours, I used several car jacks and plywood caul plates to apply pressure against the side of a brick building. The spring suspension ont the MH was not enough to react the pressure from the car jacks. In retrospect it would have been more stable if the hydraulic jacks were down. Do you know what the substrate is under the delamination? If it is luan and dry rather than particle board and you can push it in with your fingers you should be fine. If you think moisture is still there polyurethane glue will react with moisture and still bond well where as epoxy won't. Good Luck on your project.
