So as it turns out I was kinda wrong and right.
The head of every screw holding the drip rail on is rusty as hell. However the only rust on the side is where they failed to caulk the underside.
So I am going to caulk it and ignore it, knowing that Jayco did a cr@p job and that this driprail will fail and delam down the road.
Looking at the picture thats a sure sign of lack of maintenance.
Either the gutter was full of debris for a long period of time allowing water to lay in that area getting into the snap in trim, or the snap in trim cracked or pulled out of the extrusion. The screws would not rust that much on a 2016 in a few years unless something allowed water to be in constant contact with them.
You can blame Jayco, but thats the same way just about every, if not all manufacturers do a roof termination at the sidewall. The top of the rail appears well sealed to the roof membrane in the picture.
