I have noticed that along the curb side of my coach the vertical aluminum body seam located about mid-ship is separated and pulling away a little from the structure behind the aluminum skin.

Other than a place for water to get in should I be concerned this is a sign of inner structure problems? Has anyone else seen this on their coaches and is this a normal GMC thing?

This same seam on the driver’s side seems to be riveted from the factory but no body rivets were used on the passenger side.

I did read about middle age sag. I did not know if that affected the 23’ coaches as well. My door does fit nice and closes well.

Bill Bryant may chime in here, but the use of rivets did decrease after the first few years but my understanding is that they were still used judicially as necessary throughout production in problem areas on particular coaches. However, I would not allow that to linger and figure out a way to re-bond or rivet that side as well. I wouldn't allow it to stay that way.
