Chf
Since the CHF is only applicable to the F53 chassis, not the E450/350, I would start with weighing the rig for proper inflations, alignment/casters and the Saf-T-Plus which is not a true steering dampener but a return to center device. I emphatically also suggest rather than taking a poll, you deal with a reputable RV/truck service center and tell them what your specific rig is doing during the drive that you do not like. Not Camping World.
