My door tag states that my rig's gvwr is 16,000 pounds with the original 3.54 gears. I swapped them out with a fellow TDR member for his 4.10s. According to the shop manual, my rig with 4.10 now has a gvwr of 19,000. "IF" I were to be pulled over and weighed by the "law" how would I prove that increase? Is there a way to get the factory tag modified to reflect the new gears?
