Add more tongue weight. Your going in the correct direction, you just need to go more.
Correct, truck caster will not cause trailer sway BUT truck caster may play a big role in the overall corrective action required to trailer sway. IMO, without sufficient truck caster, the required corrective action would be required by the driver and the driver is usually 180 degrees out of phase to the required reaction. Again, IMO, having sufficient caster will dynamically/automatically dampen the systems response to sway long before the driver even notices the problem is starting. IMO.
What I am suggesting is a "lateral" porpoising, which is more commonly accepted as vertical porpoising in aviation circles.
Pilot Induced Porpoising
