To the O.P.'s question: I have no direct knowledge of the factory air suspension on new trucks. I do have first hand knowledge while following a new 3 or 4 series Dodge with air suspension. Of course I was very interested in watching how it performed generally on the highway. The truck had no load; no leaf springs; no coil springs. I was shocked. What I saw was a dually axle completely out of vertical control with the axle frantically jumping up and down with seemingly no control. It was like none of the tires were balanced. I did see some big shocks but they seemed to have no effect. The truck could not have been a year old.
I am not sure what you where following but the DRW does not have a air suspension option without leaf springs. The 3500 SRW/DRW setup is an air assist and has 2 thick leaf springs. The 2500's, which are only SRW, have to option for air only but that wouldn't be what you where following if it was a DRW.
Have you paid close attention to a leaf sprung DRW?? They jump and bounce all over the place too, and is why the cab stays stable.
Most people would be very surprised at how much a suspension moves around without transmitting the feeling into a cab.
