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.
