Payload & RAWR if one cares about ratings.......
Otherwise you can justify being overloaded like using air bags (which do NOT add any capacity)
But you're only overloaded on paper since you have the same axle and chassis save for spring rate/design as a much heavier paper rated truck.
Same truck as the OP describes can have over 7klbs rawr based on the weak link of tires, right off the dealer lot. Up that again by a couple thousand pounds if you add 2 more rear tires and some more spring rate....factory.
One of these days, I'd like to see what all the weight police on here used to pull or haul back in the day when a 390 or 454, 3 speed auto, drum brakes truck with 16.5 rims and bias tires was all you could get.
