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.
