We do experience slight chucking on those god-awful concrete road sections that are uneven... I40 west of OK City has been the worst for us!
The air bags and also the TrailAir flex pin seem to dampen it... I have been behind other 5ers that were doing much worse. I also think the air bags have improved crosswind stability.
