We've had our rig since 2012, and shortly after purchase we upgraded our manual slider to the 2900 ISR Superglide hitch. The pinbox has been great, quiet and low maintenance. And, very rarely do I have to adjust the tension bolt at the front of the hitch that keeps it from banging when starting or stopping. Our rails are so tight that the hitch does not move at all, and the few times I've had the hitch out, it was difficult to get it back in to the slots. The instructions for the hitch say to adjust the legs so they are tight in the rails so it doesn't move. And yes, no matter what you have for pinbox or hitch, some roads are just going to cause chucking due to how bad the road surface is.
