1. The best way to manage "bouncing" is with proper tongue weight 10-15% of gross trailer weight. When in doubt, more tongue weight is better, unless other limits such as...tongue weight, TV rear axle weight, etc. are in jeopardy.
2. The best way to manage "sway" is....wait for it....proper tongue weight, along with not driving too fast. If you have your tongue weight correct and you are getting sway at 45 mph, think about your side/wind profile, but realize you can't change it. Sway control will be helpful, along with not driving in high wind conditions. If you are fine at 50 mph and getting sway at 65+ mph, you are driving too fast. Slow down and don't be a jackass. You can tell someone is a jackass because they prattle on about how safe their rig is driving down the highway at 65+ mph. They will frequently say things like "I tow at 70 mph all the time and have never had a problem" and other piffle. And yes, that is a 100% reliable litmus test on jackassery.
3. The Andersen WDH also works on friction/torsion which is why it helps with WD and sway. So technical solutions do work and have benefit. But you should already have dialed in your tongue weight before resorting to such technical measures. They are NOT a substitute or crutch for not addressing tongue weight.
4. It's spelled "rhythm".
In summation: Get your tongue weight right. Don't drive too fast. Don't drive too fast for conditions. Get WDH and Sway Control after those are squared away, not before.
Neither WDH nor sway control nor torsion hitches or any other gimmick/technical measure are a substitute for having enough tow vehicle and understanding the dynamics of the various limits, and making prudent decisions.
THE ABOVE HAVING BEEN SAID....with super low trailer weights like boats under 15', teardrops and small utility trailers, the weights involved are so low that 10% difference in tongue weight could be a burger and fries in a bag and those are going to be squirrely pretty much no matter what.
Tongue weight is almost perfect, tow vehicle is not bad, maybe a tad lite but should be fine. I took my motorcycle out on the same road and the bike was doing the same thing, the bouncing "rhythm" was the same. I usually drive 65 mostly so I keep the speed within 5 mph but never go over 69. 69 is a good number, I like it for some reason I don't know why.
