I installed a 5th Airborne air ride pin box on mine a number of years ago. (just had a standard pin box) Helped smooth the ride as it cushions the trailer from the truck. In the rear view mirror I can see the trailer moving up and down somewhat independent of the truck over bumps and dips.
And while I had very little chucking to begin with, the 5th Airborne eliminated almost all of what there was.
Install was easy. An extra pair of hands would have helped, but I did it by myself with little problem. I like the 5th Airborne as the air bag and shock is enclosed inside the pin box rather than out in the open.
