Have a 2006 Chevy Silverado 1500HD. Came with a class III 600lb tongue weight hitch. Seems to be the weak point.
The OEM hitch on that era of GM truck was a total piece of junk. Do a search on this site and you'll find all kinds of conversations that happened in the past about these receivers and the multiple weak points.
A good
Class IV/V Receiver like this one is what you need on that truck. It's true you don't always need a WD hitch, however I've always found with heavier tongue weights using WD makes the connection feel much more solid and you get less bounce in the rear suspension. The kicker is always going over bridge joints you can get into a porpoising condition without a WD hitch.
