Work on your existing rig.
Trailer -Dexter ez ride or Morryde equalizers , pin box change to something with flex ( roto flex, morryde or an air ride), tire pressure set to max load.
Truck- sulastic shackles, air bags adjusted to get you just onto the overloads, better shocks, tire pressure set to max load.

Trailer changes helped a lot ( I did dexter equalizers and moryde flex pin box)
Sulastic shackles helped with empty ride, shocks and tire pressure helped as well.
Things that worked for me.
