More importantly, the design of the rear axle enables a “full floating” configuration. That’s when the axle shafts only transmit the torque, but don’t actually carry any of the vehicle’s weight. Instead, the bearing hubs (at the outer ends of the axle) carry the truck’s weight. The design is significantly more robust than that of a weight-bearing rear axle

Yes you have an extra set of wheels and tires, I am fine not having them.
As far as the rear axle, The single wheel diesels have full floating axles as well......
The rear brake rotors are actually a smaller diameter, on the dually. Yes you get a slightly larger pad, but rotor diameter is more important.
