Compare to the B&W that has it's pivot point at the height of the kingpin.

I agree, the hitch is the common part that has been used with both trucks.

Just to give as much info as possible here. The same hitch has been used on 4 trucks, two diesels with the 10-speed allison and two gas HD's one with the 6-speed and the current one with the 10-speed allison.
3 of the trucks had the factory puck system, one I installed bed rails and bought new legs for the hitch but used the same head.
Truck # 1 was a gas engine 6-speed 2500 hd crew cab short bed 4x4 with factory puck system. Installed timbrens to correct any driveline angle issues. Had a new torque converter installed as well as transmission pump. Assuming it was the truck... I traded for truck number 2.
Truck # 2 was a duramax/allison crew cab short bed 4x4 with bed rails but same hitch head with new legs.
Truck # 3 was a duramax/allison 3500hd crew cab long bed SRW 4x4 with factory puck system and reused original legs on original hitch.
Truck # 4 is a gas/allison 3500 SRW short bed crew 4x4 with factory puck system same hitch and legs. When I installed the hitch in this truck I made sure all bolts were tight and have the feet/cleats locked to the bed tighter than I ever have. (this elliminated any slop in the hitch when starting or braking and I have zero "clunking" slop.
My first thought was driveline shudder which is why I have installed timbren SES on all of the trucks and the "tugging" is there with our without them so I've pretty much ruled out driveline shudder since the timbrens keep the truck pretty high in the rear. But I enjoy the stability they provide so I've kept them on each truck.
I know 4 trucks is a lot in a couple years... And no, I'm not wealthy but I work at a chevrolet dealer so I've been able to play my cards right in regard to the flucuating market and trade values. I have been fortunate enough to be able to trade often without really costing me any real money.
The trailer brakes seem to function as they should and there's nothing I can see that would indicate a worn or out of shape drum, though the drums and bearings are about the onluy thing I haven't pulled apart.
I just had all four wheels off when installing new tires and all were retorqued. Again, same tugging as before with the old tires.
The unit has the "road armor" suspension. Possibly the axles are bouncing or hopping when being pulled at certain frequencies?
I'm honestly boggled. I've learned to live with it but assume something is causing it and may have bigger consequences later on down the line if I can't address it.

We're pulling the trailer to Myrtle beach next week and this will give me an opportunity to test some of the suggestions on here. Will report back.
Maybe I can talk the wife into a new hitch to see if that helps
thanks

What took you so long . It's sure possible it's the hitch . He is a great candidate for the Andersen , and IMO would solve his problem . I am sure you will agree on the Andersen with the weight he has , no need for some expensive hitch .
If they made it to attach to the pucks instead of relying on thin beds to support the fore and aft and make the tubing stronger I would consider it for a 12 RV.
YES the CURT can cause a chucking sensation that's a fact.

Some trucks are more prone to it than others, depending on driveline type, wheelbase etc. They are fine at normal ride height until a load is applied and it changes the u-joint angles enough to create a shudder felt on accel from a stop.
I had a similar issue but with a Ford, actually a couple of Fords (all LB CC DRW) It was finally determined to be just that driveline shudder / driveline wrap, most likely due to the carrier bearing being "soft" and allowing the driveline to whip around, as CC, LB has a long driveline.
Were all your trucks the same? CC/LB..ETC?
Do you know any Ford or Dodge owners? Perhaps a test tow with a non GM is in order.

You do realize they redesigned the Andersen after the problem with what a couple bent hitches ,and since we have had no reports of bent tubing . And as you know shimming the valley on the bed cures that problem . My son runs the Andersen with a bit heavier fifth wheel than the OP ,and there has been no bed deflection . I do believe they have changed the base a bit also .
To be fair ,there has been hitch failures across the board ,so to single out the Andersen is a bit unfair . Also there has never been a fifth wheel come undone with an Andersen . On the other hand how many fifth wheels have dropped on the bed of a truck with every conventional hitch made . Impossible to drop a fifth wheel on the bed of a truck with the Andersen .

They are still having issues. Look at the youtube video "Why We Ditched The Andersen Hitch".
I did s simple search "Andersen Ultimate 2 hitch failures".

They have all been crew cabs but both long and standard beds. Though it could be the driveline in all of them. Unfortunately I don't have any friends with hitches on their trucks that I could test out.
I've read a good bit on the issue and know that some ford diesels had a similar issue due to accelerator pedal input or something similar. I thought it may have been that issue since they're all drive by wire now but it does it even when using cruise control which elliminates the possibility of my foot bouncing on the throttle.

There are just as many "why we love the Anderson hitch" articles out there as well.
Most people simply hate the Anderson hitch because of stuff they read on the internet which is ALWAYS overblown and exaggerated.
Almost none of their reasons come from first-hand knowledge, just hearsay.
ANDERSEN HITCH FAILURE RATE
It’s impossible to determine the exact failure rate of Andersen hitches as the majority are only minor and go unreported. Most drivers deal with the hitch failure themselves without reporting it or taking Andersen to court. There have been no major court cases involving damages caused by an Andersen failure.
Just say no to the payload police ">

Just curious. Have there been any documented hitch failures for the Hensley TrailerSaver BD series?
