I am looking pretty seriously about an air ride hitch for the 5er. I also bought a conversion kingpin so I can pull the gooseneck with the same hitch. They seem like it would really help the ride but have no idea as to which brand. Some replace just the head and some have the whole hitch, some are powder coated and some even hide the air lines so they are not visible. I would really like to make a trip with one to see if they are worth the money as I know they are very pricey. Your thoughts and insight to these would be very helpful. Thanks, Okie
