The interesting thing about truck commercials (all of the manufacturers) is that they never say that the "payload", "torque", and "towing" numbers they throw out are for the same truck.
Payload may be for the stripped, work cab unit with the smallest, lightest gas engine.
Torque is for the big diesel (a heavy engine) and you may not be able to put all of it on the ground anyway.
Towing is for some theoretical truck that was never actually built.
No one truck can do ALL of the things claimed.
