Well the payload on the weaker C channel chevrolet 1500 is 2123 lbs, and 3760/4000 (depends on 4wd option) for the 3/4 ton. What is the Titans?( I honesty don't know) Yes I am aware of the fully boxed frame that they use, ford does the same thing with the new F150, and in theory it is stronger than the F250/350 frame, kinda funny. I applaud nissan for thier effort, but they have some catching up to do with the Tundra having a headstart.
