More information would be helpful:
What coach?
What chassis?
Have you checked the SWAY BAR MAIN AND END LINK BUSHINGS?
Tire pressure correct for your actual axle weights?
If air suspension, have you checked RIDE HEIGHT?
The more information we have the better we can address your question.
I installed air gauges to the four air bags in a Country Coach. LF 40psi / RF 40psi / LR 100psi / RR 60 psi. The coach was new, sway bars, tire pressures, height control valves, all systems and parts in perfect condition. Took it for a test run, in a long sweeping right turn at 10 mph under the posted, the LF and RF slowly equalized. The LR climbed to 120 psi and the RR went down to 40psi.
