So ---- remember the old horse power wars??? The ratings were always "fudged" by the OEMS picking the RPM's they used to show HP.... we know now that those numbers were mostly marketing BS or a way to trip up the insurance companies....
Now here's the latest OEM fudge factor.... "the tow ratings"
The 5.3-liter V8 Crew Cab 4x4 we're sitting in can tow 9,600 pounds thanks to optional zero-cost 3.42 axles. An optional Max Trailering package with 3.73 axles and stiffer leaf springs will boost that to 11,200 pounds: The 11,500-pound advertised maximum tow rating requires the 4x2 Double Cab configuration. Add the mighty 6.2-liter V8 and it nudges to 12,000 pounds.
Of course GMC, like Chevrolet, has decided to ignore the new SAE tow rating procedure that would make these numbers relevant to the competition. As it stands, the ratings are only useful for comparison within the GM family.
