Engine bay/storage area panel material

[haknslash]

Is it treated wood or fiberglass under the carpeted wall sections on the side of the engine/rear storage areas? I plan on finally mounting my onboard charger this week and I haven't peeked at the panels a lot to see what's under the carpet. I imagine it's treated wood but just want to confirm. I'm going to use stainless hardware of course.

My 08 is plywood most likely treated. I'm sure it's the same as newer units.

Yes, those bulkheads are plywood covered with carpet.
