I don't know the ratings of a Class III vs IV hitch, but the reason GM may not put the Class IV on a 1/2 ton is to prevent people towing too much? Then again, you can pretty much put any hitch ball on a ball mount.

I don't know if it has been covered yet in this thread but DO NOT SHIFT TO MANUAL when moving!! We had a crew truck with this transmission (only chev in the fleet to lol) and I was with the crew chief on a job shortly after he got the truck. On the highway he goes "what does this do?" and puts it into "M" and we go from 100km/hr to a nose dive in the highway as it goes into 1st gear... with several thousand pounds of gear in the box and cab of the truck + a quad on the deck ontop of the box..

That is why you can not get a class IV for any 1/2 ton, GM like other manufactures have to do the thinking for others and stop people from doing that, over loading the tow capacity and weight on the receivers, this is one reason I do not remove the spring bars on my hitch system when I back into a camping site.
Now the first pic is the receiver on my 2008 heavy duty 1/2 ton and is a class III, As you can see that the construction is single wall.

The rating on this receiver is....5,000 lbs maximum trailer weight with a maximum tongue weight of 600 lbs. This is with out any weight distribution just straight up towing.

The second rating on the receiver is with "weight distribution, 10,500 maximum trailer weight and 1,100 lbs maximum tongue weight.

The second pic is a class IV which is on my old tow vehicle which was a 1997GMC Suburban 3/4 ton, as you can see it has a double wall construction, I do not have the info on this receiver but from what I remember it is rated for a 12,500 lbs maximum weight trailer with a weight distribution system.

The newer class IV receivers from GM on the 3/4 ton are not double wall constructed and welded they have an insert or sleeve that slides into the receiver before the hitch go's in....I don't know why they just don't weld the darn thing in place.

Are you talking about the 2011s? Yes, there is a reducer to go from 2 1/2" to 2". If the reducer was welded in, would that not make the receiver useless for anyone w/ a 2 1/2" hitch?

I do know that in 2008 GM had an insert because I question them as to why my hitch was sloppy in the 2008 pick up and not in the Suburban, that's when they handed me the insert, but the insert would not go in to the receiver and that is when I found out that there was a difference between the receivers.

As far as a 2 1/2" hitch to be quit frank with you I have never herd or seen one, but at the same time it would seem to me that if there is a 2 1/2" hitch for a receiver then I would think that it would require more support then a single walled constructed receiver.

We use the 2 1/2" hitch all the time on the 3/4's we use in the oilfield. Especially with a three way ball.

I agree. The Class IV receiver on the GMC HDs can handle the 2 1/2 inch shank and associated loads just fine. Its a pretty "beefy" arrangement.

Thanks for the education, I did not know.

I can see where that would be a problem. On my 2010, shifting into M at any speed leaves the transmission in the gear it is already in, and simply lets you then change to other gears using the up and down button. Sounds like the one you describe wasn't working properly. I've never had a problem doing it on mine.

I have been thinking about this as well. Next time I am in the truck, and in a safe area, I will try this. I seem to recall the one time I used M:? to try engine breaking it was in the current gear and I had to "button down" manually. I truly don't remember now. I will check next time I go out.
