OK.. so.. What a mess. I managed to pull down (after a lot of rusty VERY long screws being removed, the ceiling of the engine bay on the passenger side.

Looks like above it is a blue insulation board, then some kind of plywood/OSB mess that is mostly rotted (back 2/3rds) then some kind of vinyl heavy fabric then some mylar silver bubble insulation and then the diamond pattern engine bay insulation fabric. All this is in an aluminum frame. It looks like there are slots for pinching various layers and then the screws go through the aluminum frame and then up into the frame above.   I think!

Looks lik,e the leak is coming from the front right (outboard) corner of the ceiling, That measure out to between the toiler and shower tub in the back. However, sure looks like this water was coming from both the top of the engine horizontal door weatherstripping which never fit right and maybe also the rear cap seam... but that may just be my imagination. I checked the toilet and it's holding water, flushes with no leaks and no visible water anywhere in the rear bath. I'll pull the access panels for the shower valves and tub tomorrow and see if there is any other damage.. Who knows.

Any help getting this redone would be gratefully accepted!
