Air ride 5th hitch..
I don't know the pressure off hand but air it up above the white line about 3/4 of an inch. It has an air compressor built in but it's the one that's controlled on the side of the hitch, not in the truck and auto adjusts.
Guy I bought it from had a Mor/Ryde pin box and said the combination worked really well together. Trail Air has one very similar to the Mor/Ryde now, I think either would be great.
I have heard that having both an air ride pin box and hitch can cause them to basically pull against each other but don't know if that's true. My trailer pulls much better now with the TS3 and I just have a standard Lippert pin box. It's so good now that I don't see it getting a whole lot better but have heard with a Mor/Ryde combination it's just about as good as it gets. If I keep my current trailer I'm going to try the Mor/Ryde or similar Trailair.
