Just took mine off. Truck in sig., trailer is ~7880 lb loaded, TW of ~925, or about 12%. 32' long. I had full water to try to get the TW up.
With my F-150, front rise was 3/8", and I was able to get it back to zero by tightening the Andersen to "9" threads - about as tight as I could get it before the supplied socket ran out of bite. (started with the nut flush to the bolt when hand tight).
Several small instances of sway observed, and one bigger instance that set off the truck's anti-sway system/warnings.
Great concept, but I think I just overwhelmed it with too big of a trailer. Maybe if I could get the TW up higher, it would have resolved, but I kinda doubt it - too much tail wagging the dog for the friction material to prevent the motion.
As noted, a great hitch for smaller rigs than mine. But they seem to be very optimistic in how big you can go using their hitch.
