Mich F, Did you do a rebuild yourself? Got any pics?
I see some small spots on the inside carpeting from the cabover lights. It looks like the last person who sealed them sealed the top (protecting from gravity fed water) but didn't seal the bottom (protecting from wind driven water).
I've been taking the screws and trim pieces out of the cabover in the past week or so and it looks like the "floor" of it is split into two sections. The rearward section is trimmed into the E-450 cab and looks like it has the least trouble. Because of the connection with the cab, I'm going to leave that alone. I don't want to mess up the seal above the driver window.
The front section of the cabover looks to have a medium amount of water damage. The curved wall pieces up front being the biggest issue. It's pretty soft. The flooring of the front piece has had some water in it too.
The front driver-side wall in the cabover has all of the screws out. It's build out of about a 1.5" thick white styrofoam with a real thin wood panel over it and then a plasticky wallpaper on top of that. Even though all the screws are out, I can't get it loose enough to look behind it. I'm not sure how it's attached. Could be glued to the outside fiberglass I guess...?
At this point, I know I can seal the outside pretty well with eternabond, and unless it's driven, it's covered. Further damage is unlikely, but it'd be nice to seal the inside of that fiberglass as well and replace the styrofoam and/or the wood.
