A Hensley or Propride hitch will eliminate the big truck push pull.

Not exactly. While the hitch will help, you will still have the push, only it is different. The truck and trailer get pushed together as one and won’t flex at the hitch point like a regular hitch. You will be more in control and won’t have sway but you will still feel the bow wave.
