It is just painfully rough going down the road. Here are my stats
2015 chevy 2500 Duramax crewcab standard bed ( weighs 8,000lbs at cat scale)
2015 Glacier Peak ( weighs in 10,800lbs at cat scale)
Pin weight 2,200lbs at cat scale 20.3%
Drive axle 5360 lbs
Steer adel 4840 lbs
Truck tires at 80 psi
Trailer tires at 80psi
Bilstein 5100's
"Stable load" spring enhancement kit
B&W Patriot hitch
Standard Lippert extended pin box

Should I try to take some weight off the pin? Should I drop tire pressure ? Not sure where to start? I feel the weight of trailer lunging and pulling the truck pretty bad.

I looked at your numbers, and they looked okay. I don't think that you are overloaded. Especially for the tires. You are getting a lot of advise about tire pressure. If your tires say to put 80 psia in there, you need to use 80 psi for the rear tires. I use 60 psi for the front tires.
I don't know what the Blisteins do for your ride.
The B&W hitch is a good hitch, IF installed properly.
I had real problems with my 5th wheel when we first got it. The trailer was riding very rough. I put on a TrailAir hitch. It helped. It turned our that our Reese hitch was bad.
You have something wrong, and you have to find out what. Beat the dealer up to help with the ride problem. Have someone look at the hitch.
