Pnichols,
Thanks for the explanation. I do believe that the shocks are not doing their job. And the rear may be hitting the stops. But the rough riding I am talking about is rough interstate and other roads that have ripples, ridges, cupping and other rough surfaces. I am going to install Koni FSD shocks on the rear. I will report back with the results. I have owned a 36 ft Foretravel Class A motorhome and a Winnebago 27 ft Class A motorhome. Both rode like a new Lexus compared to this Class C motorhome.
