I just do not understand the sort of logic that says it's OK to load up a truck as long as you don't exceed the limits of the highest rated component ignoring the limits placed on the complete vehicle by it's assembler? What sort of illogical logic it that???
In all of the examples cited above, the MFR's rating is based on the lowest rated component, not the highest. The ratings are for how the vehicle leaves the factory.
If the MFR's rating is based on the limit of the tires, and you upgrade the tires, then it's perfectly logical that the rating increases.
If the rating was based on the highest rated component, as you suggest, then the RAWR would be 10,120 lbs, which is what AAM rates the rear axle at. And no one is suggesting this is what we should do.
If "the complete vehicle" had any other changes, then your argument would make sense. But literally nothing else changes on these trucks.
