Pogo Stick Ride or Saddle Up Your Bucking Bronco

You might want to verify your hitch setup.

I experienced some bouncing and the cause was under sized WDH bars and some hitch flex on the truck. It seemed to amplify each dip or bump. After upgrading hitch on truck and WDH including shank, no more bounces being amplified. (I had 1000lb bars, new ones are 1500lb, tongue weight 1350lb or so).

Changing WDH and hitch will not fix bad roads, but may make them less stressful.
