According to you, you don't have any trailer sway and that is a good thing, a great thing actually. Will you feel the push pull when being passed? I say you will. You can spend a few thousand bucks for a new hitch and it might be a bit less but you will probably still feel something. I have a Tundra and when I was towing with the original P metrics I did notice some loosey goosey behavior on turns. I replaced the tires with some sturdy LT LRD, pumped them up to close to 80 and haven't had any issues since. I have towed 10s of thousands of miles with my current setup and will "feel" the big trucks passing, especially if it is also windy outside. No sway at all, just the push pull that you described.
You might still need to move up to a 3/4 ton truck because of axle ratings and/or carrying capacity. Your numbers should dictate.
