The factory framework bends at the end of the hitch because the factory hitch didn't go far enough forward on the frame. You can see how one side of the frame has bent upwards, and you can see it crushed in and under.
They make plate kits to reinforce and try to repair once the damage is done, but.. they cheaped out at the factory. The good aftermarket hitches extend further forward towards the front and prevent the issue
