(food for thought) One would think because of price or whatever one hitch would be so much better than another. Didn't turn out like that for us. We still had our older hitch set up from a prior trailer when we got our newer trailer. Our older hitch was pretty pricey when new, supposed to be real good (per advertising and reviews:). Our newer trailer had a cheap EZ-lift hitch laying by the propane tanks, dealer said take it if you want it. (Ez-lift is about the cheapest set up you can get). Of course it was raining that day when we picked up new trailer. Instead of messing around with the ball mount on my old set up, we decided to use cheap EZ-lift to tow TT home. Dang it towed great. Long story short, still using cheap set up couple years later. However we did find out a few things after getting our newer trailer home. After completely loaded and ready for the road, then scaled and weighed axle by axle, and side to side. Turns out newer trailer has better percentage of tongue weight and better balanced. Newer trailer is so much more pleasant to tow, even with a cheap set up and about 3,500 pounds more than old trailer.
As far "friction sway control" I don't even carry it anymore. Little friction brake pad on an axis point of 10,000 pounds is like a finger nail file rubbing across big thumb IMO
