Bucking with Anderson Ultimate 5th Wheel Connection

I use the Andersen Ultimate hitch and pull a good sized Jayco FW. The chucking was so bad on certain road conditions it stressed me out every time we went out. After several unsuccessful changes, I finally installed a MorRyde rubber pin box. It made a huge difference. I don't think it solved the problem but dampens it enough that it doesn't bother me anymore. I would never own another FW without the MorRyde pin box.
