Ok, to any naysayer that thinks there is too much flex, take a good look at an Ungers from the late 60s, early 70s. They were hand laid up fiberglass in on complete piece. There are no seems anywhere in the shell. They built them upside down. The only seems where the floor met the side walls up underneath the coach. The glass did hold up, as I have seen a few somewhat recently.
Now having said that, I can't figure out why you would do that to a Rexhall. The roof cap overlaps the 2 end caps and the side walls, so I can't figure out why it would ever leak anyway. Its one of the very few coaches that are built that way,
