Not surprised at this frankly. When I bought my dump truck moons ago, bed hitch maker mentioned, the 1/2" pin used in most 2" hitch applications was only strong enough for a 10-12k trailer. You needed a 5/8" to get to 15-20k, and 3-4' or larger for over this amount. Hence why most tow rigs towing REALLY heavy ball or pintle hitch trailers have the hitch bolted to s frame.
One would need to up the bar size to fit s bolt that was strong enough to handle s given size trailer one might pull in this manner.

I have been using 2" receivers since 1969 and everyone used a 5/8" pin. The 2 1/2 receivers that I have seen do too. I am sure that they will have to change as some point though.
