That link by shinerbock says what I thought it would. No reference to manufacture ratings. Similar wording to here in WaSt 're RCW45. That this states weight laws and how enforced etc.
All pickups be them used commercial or personal only pay/buy tonnage in 2000 lb increments. Base amount is tare time 150 percent to next higher ton. If your rig empty is 7000-7500 lbs, that is 10500-11250, rounded up to 12,000 registered gvw. You are legal to that give assuming you paid the tonnage, and your tire widths times 500 lbs is greater than you weigh. Or 20k for a single axle, 34000 for tandem as noted. There are a few other exceptions per say.
Also as noted, if you do as I have with my C2500, my paid for registration is 8000 lbs. If I run down the road at good sticker 8600 gvw, I am overweight by 600 lbs. I've been pulled over in rigs 150 percent of manufacturers gvwr, but under FBL limits and paid for registration. I have no overweight tickets in my name, or company name.
Gcwr or its many variations, is not a legal number of any sort. Only in that the axles will be added up for max you can run down the road at, using formulas mentioned for max enforced loads.
The loads enforced by leo/cveo types, is max point load the road cab handle before road is damaged. THIS is the weight law enforced. Not the manufacture warranty/performance ratings.
