I have a 2006 Crew cab with the 6.5 ft bed. I don't have hauling or heavy loads, it's mainly used for commuter driving. my problem is on these patchwork quilt roads here in PA this truck bounces around and telegraphs every bump and crack on the road back to your seat. What can be done to smooth out the ride, remember that I don't care if i must sacrafice weight load ability (if that even matters)
