Actually, the Andersen "No Sway" might be a pretty good choice.
I made the mistake of trying it on my 2670MK, but that is twice the weight, and much longer than the 17MKE. The Andersen relies on tongue weight in the silicon cup under the ball to use friction to control movement. Sway is ONLY due to not having enough tongue weight. Should be in the range of 12-13% of your full trailer weight. A hair light, and you may get the start of sway a certain speeds, and the friction will help dampen that. Too light, and the friction doesn't help (for any brand that depends on friction) and the trailer can literally throw you off the road. Sway is nothing to tolerate. My trailer was very light (10-10.5%), so between the lack of tongue weight and the much longer tail to wag the dog, the Andersen couldn't cope. But with the 17MKE, and proper tongue weight, you will be well within its capabilities. Setting the weight distribution is very simple and easy. I had no issue restoring the full weight lost back to my trucks steer axle. And that, again, was with a much heavier trailer.
It's less expensive, very light, and easy to operate. Backing is no issue at all.
BTW - others may call things like "truck suck" as a semi passes you, or wind pushes, as "sway". It's not. Those things, or rough roads, can initiate a sway event, but also are separate disturbances to driving. The Andersen friction can help with, but not cure, those too.
Me? I had to get the ProPride, and it will cure every issue. BUT at over 5 times the cost of the Andersen...is way overkill for this setup.
