You are not alone. There have been a number of postings over the years about people realizing they had high hitched without realizing it. When someone says they raise their trailer so that the pin box is higher than the hitch plate when hooking up I have to wonder if they are on the verge of high hitching. The bottom of the pin box plate should be no higher than the top of the hitch plate, and preferably slightly lower, when hooking up to ensure it latches properly. If the pin box rides up on the hitch plate there is virtually no chance of a high hitch. And when unhooking, there is no reason to raise the trailer until you can see a gap between the pin box plate and the hitch plate. You are likely then putting an upward force on the hitch latch mechanism by the pin pulling up from the bottom.
It would be almost impossible for the king pin to pull out of the latched wrap around jaw without visible damage to the hitch jaw, the pin, or both. Probably the same with the clam shell type hitch.
