I like your suspension, how much of a load do you think it can handle. Went with trailer leaf springs on mine so it's pretty stiff. You should probably switch to an articulating hitch.View attachment 408659

With proper tongue weight, a pintle hitch is fairly quiet. It doesn't have the 360 degree articulation as a lock-n-roll, but it is better than a ball hitch. And very easy to connect and disconnect.
A correctly installed pintle hitch is designed to have 360 degree rotation.
On the light duty setups the Lynette is supposed to rotate
On the medium and heavy duty setups the pintle hook rotates
The Lunette on the 1/4 ton trailer rotated until they added the surge brakes. It does take a 6 foot bar to rotate it due to the spring tension. That is the reason there is a grease fitting on the casting
Mine is correctly set-up.
For what you're talking about in a military application - yes. However, if you've got a 2" receiver on the tongue of your trailer, they don't sell rotating lunette rings. You've got to go with a fixed unit that slides into your receiver tube.
They do sell (in Europe) a Dixon-Bates pintle hitch that can either be in a fixed upright position, or you can pull a pin and the pintle hitch will rotate 360 degrees. It is on my "future purchase" list.

You are using a "Trailer Hitch Receiver Mounted Forged Tow Eye, 10K" for a Lunette when you should be using a stud mounted Lunette
You are using an eye that is designed as a recovery point for a lunette so if you have a failure the lawyers could have a field day. That is a lot of metal to only have a 10,000 lb rating especially when you compare it to a standard 5 ton lunette.
In all of my years dragging pintle hook trailers around, a lot of trail miles, I have yet to have the lunette on either my M100 or M762 (flatbed M416) rotate. I also have yet to bind the lunette on any of my M101 trailers.
So I think you may be overthinking this.
Is you want a rotating lunette you could use one like this
