This list wash now has me very concerned. The hairline crack is now a thumb nail wide crack and also on both side of the unit...... If your having trouble trying to think where I'm speaking of if your standing in front or your outside kitchen look at the small section that is from the kitchen slide to the rear of the 5er. That corner at the top is the crack. Same location on the other slide as well. If I were a guessing man I would say the rear jacks is the cause of this issue. Thoughts?
That appears to be a anchor strip for the slide topper not installed. The slide side wall cut out has been working and the failure has propagated from the slide cutout to screw holes securing the strip. Hopefully you have extended warranty, it needs to be repaired both sides.
