Are you sure the water infiltration is not from in the wheelwell and wicking up through the lamination, or possibly a combination of that and from the fridge vent area? One thing is consistent on these things and that is the shitty construction. I have not seen any that did not have some type of unsealed gap in the wheelwell somewhere. Usually you'll even find exposed plywood edges in the wheelwell which is the substrate layers of the wall panel lamination. Spray on undercoating is a good idea in the wheelwells.
Good point of consideration, and I will check underneath further today. I haven't taken many/any recent trips in the rain, and just before I saw the delam in the past week, we had a major storm of 3-4+ inches of rain, much of it hitting that side of the camper. I double checked the exterior caulk around the outside rear fridge area, and that was fine, but the bottom right screw appears to not be as well caulked as the left one was in the picture, so I plan to reinforce that and recaulk the whole area again with Dicor.
The outlet itself is screwed into the styrofoam, so that alone too needs some extra TLC and caulking to reinforce that in too after I am done with hopefully flattening this fiberglass out with the rebonding.
I will still check underneath, but I really am suspecting that internal screw behind the rear fridge grate area where the grate cover is removed to see that item in the original picture above.
