The sliding bar type hitch is very secure, but old technology. The two jaws that close on the pin is a very common style latch used on many hitches including the much liked B&W. But I have no idea how many of those can be opened with a shovel. Personally I like the wrap around jaw type that wraps fully around the pin and doesn’t have that opening behind the pin. I had a Pullrite Super 5th hitch in my previous truck and now a Reese Elite hitch in my current truck both having the wrap around jaw and geared to the pull handle. Just seems the most secure latch method to me.
