That is a weak stress point in the wall, very common on many brands. Many now come from the Factory with a vertical cut at that point with a molding section inserted into the cut.
I would do the measurements on King Pin movement and if within specs, make a clean cut where your crack/tear is and insert a section of molding to seal it.
Agreed. One my previous 2006 rig I had a crack like that. Ran from the corner of the cut out about 3". I checked the crack with and without load on the pin box and it would open/close very little. My new rig has a factory applied vertical strip and I have seen them on many rigs.. I suspect the factory cut the side wall to allow a tiny bit of relief. Hopefully there is not a weld break or failure on your rig. Keep us posted.
The OP's rig already has the cut and vertical trim piece. It is clearly visible in the pic. That didn't prevent his failure. So it is more than just minor flexing of the frame.
