2005 Winnebago Minnie, the dreaded cabover leak

Here's a pic of one that we just put the fiberglass on the cabover front wall yesterday.

Three of us put it on, and it would have been easier with a 4th (or 5th) person. There's no second chance with the glue that's used, once the pieces mate they bond right away.
It wasn't that long ago that the cabover section looked similar to my MH on the left.
The sides still have to be trimmed, clearance lights and trim molding installed and the inside finished off.
