Why not a 2 speed or quick change rear end option

Sorry for the off topic...

It has a 2 speed front and rear axle, each with the same regular, and 2.92:1 ratio in each diff. The rear also has an e-locker, and it has a 9 speed auto trans. Complex system.

My point was that the technology is there to have 2 speed axles in tow vehicles, and I don't think that it will be long before your 2500 and 3500s have the same technology.
