I use to have bouncing. In 07 bought a trailer that came with Mor Ride pin box, and mor ride on the traier as well. Never had I pulled anything so smooth. My only problem when completely level I was too close to bed rails, and it did not drive well. I adjusted hitch which raise front just a little. This is not Kosher, but suddenly the pull was completely smooth. In 2010 I bought a 2011 Ford diesel that did not have enough suspension. Wow did it bounce. We installed air bags and it is completely controlled. bought a Cameo in 2011 and installed the Mor Ride hitch and it already had Mor Ride on the trailer axles. We really don't even know its back there. No bouncing, and no chucking. Keep trying. Have you talked to HH. They have probably dealt with every problem and should have a solution. Hope you come up with a good soution. Would like to know what finally fixes the problem.
