Payload is a marketing number. Through the years all these numbers have moved up every year when in fact the basic platform (generations) have only changed a few times. I suppose a different type of paint allows more payload than last years paint color. I think red has the potential to increase payload the most, perhaps green but I can't prove that anymore than the big three can justify why 1/2 tons of 10 years ago are 1 tons today. Its about selling trucks.
spring travel and tire load range is payload.
