You have to decide what you are trying to accomplish. If you consider the configuration of the simple air pinbox, it moves up and down on a pivot. That means it will basically cushion the up and down movement of the coach versus the bed of the truck, meaning the hitch. If you look at the Morryde pin, it moves fore/aft and sideways, meaning it's basic function is to smooth out what we call chucking - - the fore/aft jerking. Both do a good job at what they are designed to do. If you wish to cushion the impact on the frame of fiver and smooth out the ride both inside the fiver and inside the truck, PLUS kill chucking, get an air hitch such as the Air Safe. Quite a bit more money, but sure worth it. I have had all three configurations - - sure wish someone had told me to buy the air hitch first - would have saved me a bunch of money.

I installed a 5th Airborne air cushioned pin box. Somewhat similar concept to the Trailair except the air bag is inside the box and protected. I did not have a lot of chucking to begin with, but the 5th Airborne eliminated virtually all of what I did have. Plus it softens the ride of the trailer and that softens the ride of the truck. Definitely worth the money in my opinion.
chose the 5th airborne for exactly the same reason.
Here is a diagram of how the 5th airborne reacts. The Trailair would be the same only opposite because the airbag is forward of the pin:
As you can see, the 5th Airborne and the Trailair do a pretty good job at buffering forward and backward motion as well - not just up and down. Someday I want to tape a video cameral back there to illustrate the actual action while driving.

I have the Trail Aire Tri Glide on order and am anxious to get it bolted on. Hope it fixes the rather bad chucking I'm getting. Found a relatively good deal on one (assuming its delivered) $1,250 with freight from etrailer.com.
Again, I don't have it yet. Ordered it May 29th, at which time they said it should ship within 7 days. I called etrailer.com June 5th, and they said the manufacturer won't ship until June 11th, then etrailer will have to ship it to me since Trail Aire doesn't ship direct. I'll be lucky to get it before we leave on our trip out west June 21st.
Apparently the manufacturer builds these when the order is received. At least the steel won't be stale, lol.
Tri Glide TrailAir... Had mine for a while now. A combination of the TrailAir and a Demco like glide plate. Best of both worlds. Air ride for up and down and minor chucking coupled with the Tri Glide plate (acts the same as a Demco or MORryde) to cushion any remaining chucking to non-existance. I'm a convert. It is interesting watching it in the rear view mirror doing its thing and us not feeling a bit of it in the truck.
Boxer Lovers...you'll love it. Well worth the wait and I hope you get it in time to get it installed prior to your trip!
My 2 cents, your mileage may vary...

Thanks for the replies guys. I notice more of the chucking than anything. My local dealer has a new mor/ryde sitting in his shop but wasn't really interested in it. Better yet it is the wrong pin box for my trailer so now I can do some more research. After reading the post I checked out the tri glide from Trailair, looks like a good unit for doing both jobs. Called dealer from work asking for price and haven't heard anything back yet. If purchased form a on-line dealer, would I be able to do this install my self? Doesn't look complicated unless I'm missing something.

I got the trailair a few weeks af I got my TH, it helped with 90% of the up and down, very little of the front to rear (I didn't haul it THAT far with the solid pinbox, so take that with a grain of salt). Added the triglide (FAR cheaper to do it at the same time, cost me over 400 extra plus shipping to do it a year later). That helped with the front to rear chucking some.
Just got back from a trip to Santa Cruz, over highway 17, there are 2 or 3 places where it still chucks - just a bit - not bad for 2.5 hours and a mountain each way.
