TWP is right, sway, bounce is not an option its included when you buy it. You can mitigate it to the point its not really noticeable except by those who have nothing to do.
We have very little bounce or sway, certainly within acceptable limits of anyone, even my engineer wife and I to am an engineer.
I will give you some tips and let you take it from there.
There are 8 (unless you have 3 wheel sets down) support points on most TT/5th rigs. Use them all. Generally I begin by getting my lateral and length levels by using my 2 front drop jacks. [note there are times when you must level first using your wheel sets, I find that is not often, most RV parks are near level that you do not need to put planks under the wheels]
Using the 2 front drop jacks to level out and move the lengthwise bubble ever so slightly off center so as you will compensate when you lower your rear stabilizer jacks. So the result is to center length level bubble is that you have to raise the rear of the rig....when you do this by lifting a couple of inches [you can tell by the sound of the motor slowing] you have stress the frame with an upward bow. Its not much, but its enough, the center is now stabilized by the wheel sets, the frame has some stress in it and if you are level in both directions you should have very little sway or bounce.
The frames are very rigid, if they were not, there would be cracking, leaking and a rolling disaster. By adding a bit of stress to your frame you take out some of the built in flex.
All my jacks etc are OEM, I don't use any gimmicks or something I bought on late night TV and not available in any store.
