I would be more inclined to trust this info, from GM directly:

A). What is this distinction you are making between GVW and GVWR? Wouldn’t GVWR simply be the “Gross Vehicle Weight Rating”? Or are you looking specifically for the rating over the rear axle?

B). Curb weights are historically unreliable. There are several different “kinds” of curb weight - base curb, EPA curb, plus a few I’m forgetting - so you need to know the loading condition, in terms of fuel, passengers, ballast and option content, in order for the published data to even start making sense.

At the risk of being simplistic: If you’ve weighed your truck you know what your specific truck weighs. To me that’s far more helpful than mining generic data from the Internet.
