I am very sensitive to the rocking and rolling in fifth wheels. We have triplet 8 y.o. boys so there's a LOT of commotion going on at all times.
So I had the Steadyfast stabilizer system installed. That seemed to great reduce the motions by about 80%. But we still felt the bouncing in our bedroom when the kids jumped off their rear bunks. So I installed the BAL kingpin tripod. That got us to about 95% elimination of the vibrations. I still feel a bit of it, but it's nowhere near as irritating now.
I suspect BAL tripod helped because the Steadyarm system took care of most of the motion, but the master bedroom is partly suspended over nothing. And that's where my head is. So having the tripod under the kingpin really reduces the purposing effect when the kids are jumping.
