When this thread popped up the other day, I looked into anti-rattle devices again.
The StowAway Hitch Tightener that I bought two years ago (and haven't used yet) seems to be among the more highly rated. I've avoided using it as I don't want to add bolting and unbolting it to my chores. I like to remove the ball mount once we arrive and set up the trailer, so it would be a recurring task.
Yeah, lazy Mike; doesn't want to mess with a WDH, won't even tighten and loosen an anti-rattle device. Might as well go get a Class C, eh?
Anyway, I found a couple of new designs the other day that looked intriguing, but both of them have basically disappeared from the face of the planet so I presume there was some serious defect.
I also ran across the Hitch Hugger by Dakota Metal Works. It's quite a bit more expensive than most, but apparently does not require any bolting and unbolting. There's a video on the site.

Does anyone have any experience with this one?
