I have owned many, and they all work. But the Rhino is the slickest set up. I use a 2 5/16 ball 95% of the time and the same trailer about 80% of the time. The last one I had before Rhino had not been adjusted for years. Truck (my superduty) is garaged 100% of the time it is not being used. When I went to make adjustments for a emergency trailer use, it was locked up solid and I was EPHed for a couple hours.
Got the Rhino and haven't looked back. I will agree it can look ugly but the beauty is in its function.
