I just bought the Blue Ox Sway Pro 2 weeks ago and left on a 1200 mile trip a few days later. I had a Eaz-Lift round bar with two sway controls and it worked ok but I felt more movement than I liked. I read as much as I could find about the Equalizer Hitch and Reese Dual Cam and the Blue Ox. I finally decided on the Blue Ox and am very happy with it. I called Blue Ox twice and asked them questions and was always put through to a technician right away. They recommended the 750 lb bars for mine and it was the right choice. I had very little to no movement at all in heavy winds (25-30mph) or from passing semi trucks. I was hesitant to spend the $600, but it feels much more solid and is more enjoyable to drive. The thing that really sold me was reading about the set up of other hitches. I had the Blue Ox set up in about an hour and didn't seem to have all of the set up adjustments that I read about on other hitches with tilt etc. Anyway, it works very well for my set up and I highly recommend it.
