New pin box...

I have the TrailAir and Rancho 9000 on my truck. Found that using a softer setting on the shocks and a smiggen less air in the pin box I get the best ride we ever had. They kinda balance each other.

The Demco Glide Ride was standard equipment on NuWa's HitchHiker 5th wheels.

The Demco Glide Ride was the recommendation of the service and parts manager at the dealership where we bought our Grand Design fifth wheel. He said it was the most effective and was compatible with my
Andersen hitch setup. I'm in the process of locating one while we're where my brother-in-law can help me switch out pin boxes.

Most important is the pin weight percentage.

Have you been to the scales a determine your pin weight percentage and if you have what was it?

Haven't scaled it yet. My intention is to do so in the coming weeks. Like I said, it tows really well. There is really nothing that is telling me that I'm too light on the pin(or heavy). I'm just looking to make some improvements. The only time I get some chucking is on concrete roads with expansion joints in them.

Sounds like you are near the the point of a pin box.
I would assume Great shocks on the TV, good shocks on the 5er, all is level? Not scaled yet so that could be interesting, 20% pin is a good place to start, a little more will help, dry pin is only 16.25% of Dry weight. If you load in 1,500# of stuff, you need to get the pin to 3,000#.
I will buy the pin box as the last step to 100% smooth towing, and likely a Mor-Ryde, as it is simple.

I had very little chucking except, like you, on certain concrete highways. I put a 5th Airborne pin box on mine and it eliminated almost all chucking.

I have a Mor Ryde. Got it because it was simple and very well priced. Works well.I would consider trail air as well, though.

MorRyde: simple and it does the job! Best towing upgrade for my rig.

Watching my air pin box work can be mezermizing for sure. I have to remember to keep my eyes straight ahead. Ther do work really well at reducing the reactions between trailer and truck. I still get some foreword backword clunking, but that is due to the slack between hitch jaws and pin. Some hitches can be asjusted to eliminate that also.
