I have a situation that I need to figure out when we are on roads that are concrete with expansion joints. It doesn't happen on asphalt paved roads. On the roads with expansion joints every few feet if I'm driving at more than about 50 MPH the tow vehicle starts bouncing.
IMHO there is nothing wrong with you rig or setup. MY rig does the same on some newer interstate roads. I believe that some stupid highway engineer specified a spacing between expansion joints that will cause the rig to vibrate to keep you awake or make a milkshake of your brain. I would love to be that engineer's boss and make him drive that road section continuously for a week. He deserves that type of punishment!
