Bucking with Anderson Ultimate 5th Wheel Connection

Setup:
Tow vehicle: 2015 F350 short bed with B&W Goosneck hitch and Anderson 5th Wheel Ultimate Connection and 3000lb air bags. Recently added Bilstein 5160 shocks.

Towed Vehicle: 2017 3730FL Keystone Montana. NOTE: running about 1000lb payload for a gross weight of around 14,400 at the most. I always run dry so no water or black/grey water. I generally load over the axles for balanced load.

I can get severe bucking when exiting certain fast dips after a bridge.

Any ideas what I can do to help the situation? Trailer shocks, different hitch,????

A 5th wheel is designed the same as a teeter-totter, of course it's gonna buck.

Well you have just blown the bragging rights of all other Andersen Ultimate Connection of how it solves chucking in a 5er!!

Now to the point, what is your pin weight percentage? Best towing at 20% to 25%, most find closer to 22% is a good spot.
My guess is that you are pin lite, so that the 5er is trying to rock back and forth on the axles.
Is your FW tank forward of the axles, if so try filling it full and see how it tows. You likely need to get pin over 3,100# and it will get smother. To your question on 5er shocks, they will help.
