On am on my second TrailAir pin box. My first one was purchased from PPL Motor Homes on line for my 2010 Cougar. I installed this in the fall of 2010 and it was still on the trailer when I traded in for our new Cedar Creek. This was one of the best items that I purchased for our Cougar. When it came time to order our new Cedar Creek, I was glad to see that this hitch was offered as an attachment. Because I will never tow another 5er with out either a air ride pin box or air ride hitch.
There are two types of TrailAir pin boxes that I am aware of The original TrailAir and a new Tri-Glide box. The Tri-Glide also offers a similar back and forth motion like the Demco Glide or the Morryde box.
