We had a Mor/Ryde pin box on the previous two 5ers. It does stop the chucking. It does not stop the vertical impact on the trailer pin.
The air ride pin boxes lessen the vertical impact on the trailer and will help a bit with the chucking.
What I have that works now is a Trailer Saver TS3 air ride hitch and a Demco glide pin box.
Makes a much nicer ride for the truck and trailer.
