Question Ultra-Fab Trailair v. MOR/ryde 5th Wheel King Pin Box

So I really wanted a Reese Airborne Sidewinder king pin box, but I recently discovered that it wouldn't fit my king pin box :( I've got the Fabex 730 & my service technician & Reese have both confirmed that the Airborne will not go on my 5th wheel. Now I'm looking at the Ultra-Fab Trailair Air Ride 5th Wheel King Pin & the Cushioned MOR/ryde Fifth Wheel King Pin Does anyone have any direct experience with either or both of these devices? Any stories, advice, etc would be much appreciated. Thanks in advance :

My 5th came with the Trail-Air. The wife hated the jerky chucking when we went from the West Coast to Indiana, so I had Mor-Ryde replace it with their product. She is a lot happier now. The Mor-Ryde has since been to Alaska 3 times and she never complains about the ride.

I had a Mor-Ryde on my 08 Jayco Designer and it made for a really nice ride. Took most of the jerk out. I can't compare to the Air Ride because I haven't used it, but we were totally satisfied with the Mor-Ryde.

Great to know all the positive stuff on MOR/ryde, especially since they're cheaper! I think I'll go with it.
Thanks everyone

I Have found the Trail Air to be very jerky as well. It almost feels to me that the air cushion allows for too much for and aft movement under acceleration and hard braking. I now have a Mor/Ryde on the new coach and the ride is much better. No where near the same amount of movement.

I hate to mention "more money" - BUT - - a good full motion air hitch will give you the best of both worlds. A four bag hitch like Air Safe will not only cushion the up and down movement but will cushion fore/aft and side play issues. This then reduces chucking (fore/aft) and the up/down movement that bounces the truck and trailer up and down. This dramatically reduces the strain on the kingpin framing. We put on the MorRyde kingpin and were very impressed with the improved ride, but not totally satisfied. A failure of my kingpin framing (and $3000 later - - thankfully paid for by Carriage) sealed my mindset of adding the air cushioned hitch. The improvement was very noticeable. If you are investing, consider going all the way on something that will stay with your truck when/if you trade fivers.

I have had several Mor/Ryde pin boxes. They have worked well for me.I cannot speak to Trail air or an air hitch.
