On our way to Texas, as we would go over rough sections of road, I would notice the front of the trailer cycling up and down out sync with the truck. It was a nice, smooth action but I’ve never seen that on any other trailer. I thought it must be some type of MorRyde product but when I contacted them they said they don’t have anything like that. The reason I contacted them was because I would like, someday, to replace the standard MorRyde pin box with a horizontal shock absorbing one and want to make sure it would be compatible. We had one on the last Carriage and really liked it. Any idea what type of product I have here?

Randy,
I have the 4-bag AirSafe 25k hitch with Binkley head. I think they only come with that head now. Mine is almost 11 years old now with 40k miles towing the 36fws. Zero problems. I replaced the shocks last summer – was probably overdue because I noticed the difference.
I have the MorRyde pin box. Great combo. No need to remove it.
The MorRyde pin box deals with fore-aft chucking only. What you describe does not seem normal unless you have something other than a MorRyde pin box such as the air-bag TrailAir pin box or you have some king of air-bag hitch already.
If you have neither, I suspect that your 5er frame is flexing too much in the pin box area. There are several postings and strings about such frame issues and some relatively easy fixes and a couple of more complex problems.. Phil (jdpm) even posted a video but I think he decided nothing was wrong. Popped screws on the molding holding the front cap in place or excessive popping when using big foot to take pin-load off the truck or when hooking up are indications of excessive frame flexing.
As an aside, I replaced the white donuts and the big rubber “shock/spring” inside 2 years ago. That I should have done sooner because everything was so rusted being here in Florida. The insides of the MorRyde has safety brackets in case that rubber fails. Such a failure would nresult in some serious clunking noises when traveling, not the “smooth action” you describe. So i think your pinbox itself is fine. The 5er frame area it attaches to what I question. More info from you per jdpm’s post would help.
Regarding an upgraded hitch for the truck, AirSafe had a used almost new “for sale” Accessories posting here a while ago. These hitches do an incredible job of absorbing the up and down motion. There are other manufacturers and approaches out there.

John,
The label on the pin box says “spb72-700″. The reply from MorRyde was that stands for ” straight pin box “. From my position in the truck it appeared the movement was well above the pin box. Just reminded me of something being dampened by some type of shock absorbing product. We don’t have the MorRyde suspension, unfortunately, but the trailer does ride pretty smoothly. We’re on site now in Hill Country and, as soon as I get a few other things resolved, I’ll open up the overhang and see what is up there, and if anything is wrong. I’m pretty satisfied with my new B&W Patriot hitch but will consider a MorRyde pin box in the future.

Randy,
I do not understand. Do you have a MorRyde pin box that looks like this or not?
The MoreRyde suspension is entirely different. Very few had the MorRyde IS system from the factory, but almost all in model year 2010 (09/09 build dates) and later had the MoreRyde RE (equalizer) suspension from the factory. Neither suspension systems would display symptoms you describe.
the b&w Patriot is a rigid hitch but with jaws similar to the Brinkley. Definitely not the source of any flex going down the road.
How long have you owned this 5er?
good luck.
