Pre CHF and with no other chassis enhancements the coach would sway heavily in turns. Body roll due to wind, weather or large passing vehicles, was very noticeable and required steering to counter. CHF reduced the movement immensely. If the suspension stiffened up I didn't notice it but then I don't have a Jeweler sitting at the dinette splitting diamonds.
