The owner's manual for your truck says "do not exceed ANY rating," period. It does not say "GVWR is just for taxation and licensing, so you can safely ignore it," anywhere.
Nor does it say "the limits are strictly safety and engineering oriented, specified solely by the engineering team with zero input from the lawyers and marketing"
Ever tried to find the equivalent "tow rating" on a Class 8 tractor? (Volvo, Peterbilt, Kenworth, etc). Why do you think that is? Because Kenworth forgot to put in a tow rating?
No, because in the commercial hauling world, the only safety engineering spec that DOT cares about are tire and axle ratings. Don't exceed those, you can haul any weight so long as you pay your taxes and licensing.
Also, Kenworth knows a CDL driver will not, and cannot sue them because he's driving like an idiot and blows a tire while towing a trailer. Whereas Joe consumer will likely sue GM when he drives 80 mph with a 25k lbs 5th wheel, loses control and crashes. If GM didn't put in a "tow rating"...
