I am no scientific rocket, but you may have just answered your own question. If the higher cost hitch solutions inherently have the slop that you are referring to, then wouldn't they be the source of the problems?
I understand the difference between chucking and slop. So FYI chucking is the pushing and pulling that occurs between the truck and fiver as each react to road surface variations at different times. This effect can be minimized by better suspension (truck and/or trailer) and better isolation between the two with those expensive hitches and pin boxes and of course better roads and lower speeds. This is very similar to driving a single vehicle on a washboard road. Speed makes a big difference and each vehicle acts differently. The slop in a hitch doesn't cause chucking, it just creates noise as the truck and trailer move independently either due to chucking, braking or accelerating. And as I stated, these forces between truck and trailer are going to be the same magnitude regardless of hitch type. The Andersen has no isolation so forces are instantaneous, the slop in standard setups result in delayed forces, and those expensive setups actually cushion the forces (more or less).
The Andersen Ultimate is probably the best ball mount solution for fifth wheel towing when a GN is absolutely necessary, but few of us need to tow GN units. Otherwise, like every other option it has it's +'s and -'s.
