2500/250 trucks have always had 2.5 inch shank receivers, I think. My 2010 2500HD Chevy does. I changed out the 2 inch shank on my Equalizer hitch to a 2.5 inch shank. I figured it would give me an added degree of safety and hopefully less wobble. It is really heavy now, and I did not notice much of an improvement in wobble. I later added an heavy duty anti wobble clamp device to completely eliminate wobble.
By "always", you mean the last 10-15 years. Maybe that's always in your experience?
