New 5th wheel doesn't tow well

Since I posted this, I have done a lot of reading about 5th wheel chucking. Apparently it's a common problem and a phenomenon that may not be eliminated at all but simply masked but adding buffers at the hitch point to soften the shock caused by chucking -i.e. air bag pin boxes, rubber damper pin boxes, etc. I've also read that replacing springs, shocks, air bags on the TV won't change a thing except the balance of your checking account. I also know that a lot of people do not like goose neck systems or any variation of the goose neck hitch. The Andersen hitch changes the basic design and really the only common thing about the Andersen and a goose neck is that it uses a ball, but that ball is at the pin box instead at the bottom of a "neck" extending down to the bottom of your truck's bed. Anyway, the way I understand it the chucking motion is created by opposing lateral forces between the vehicle and the trailer when hitting bumps or dips in the road. Granted, this can be amplified by looseness or flexing at the hitch point.
For sure it's not going to be an easy thing to remedy and probably will be a process of trial and error. My reason for posting this was in hopes of finding someone that's already been through the "trials" so I could save a lot of headaches and $$ along the way. Thanks for all the input so far.

Been there, done that. Trailer in my signature tows at 10,000# with 1,800# pin similar to yours. Chucking was horrendous with our heads bouncing off the headrests. Tried Bilsteins - no help, tried air bags - made it worse, even took off the helper spring on my 3500 - no difference. Let's face it, for reasons that I will skip here your trailer is making fore/aft motions and your hitch is very effectively transmitting those forces to the frame of your truck. The fix is to isolate the trailer chucking forces from your truck. Air pin boxes and air hitches and isolation pin boxes such as MorRyde all help. Note that the Anderson Ultimate video on the Anderson website is using the hitch in conjunction with a MorRyde pin box!

You aren't going to like this but my solution was a TrailerSaver hitch. I wasn't happy about spending the bucks but my tow went from "sell the trailer" bad to a smooth trailer isolated pleasure. Some of the best money I ever spent.
