The shape of the jaw that contacts the kingpin is not round it looks irregular. Does not seem correct?
It is correct and by design. The lower, or rearward, portion of the jaws form a perfect semi-circle that fits the pin diameter. The upper, or forward, portion of the jaws have more clearance. You can see it in my photos too, but not as clearly.
I also agree that it is crazy that he could not drive out of that in 4WD. Especially in a newer FX4 that likely has an electronic rear locker. I'm confident my truck would have driven right out of that, or at worst needed to rock it a little to gain momentum. But I've also seen crazy things before on wet grass.
With the trailer axles starting to sink in, it would be pretty easy to simply dig yourself deeper trying to get out of this type of situation. I know the great resistance and ruts created when backing my trailer over the grass boulevard into my back yard when the boulevard is saturated from ongoing rains. And my current trailer sinks much more than our last one did due to it being 4K lbs heavier.
