I have used the Equalizer hitch for the last 3 years until I purchased a larger TT last summer. My new 32' trailer is around 7,000 lbs. fully loaded, and I just could not seem to get the EQ hitch dialed in correctly. The ride while towing was rough, and I even experienced some push/pull from passing semis that never happened when towing my old TT. Came across the Blue Ox Sway Pro hitch when searching this forum from others who have purchased & towed with it. After deciding to purchase the BOSP, and towing from Michigan to Maine a couple of weeks ago, I am impressed! No sway at all, and the towing experience was so much better. The real beauty of the Sway Pro system is its simplicity. Unlike the Equalizer, the only adjustments are with chain links to transfer your weight equally over your truck axles. No noise at all turning or backing up (which used to embarrassed my other half when pulling into a campground). Don't get me wrong, both are good hitches. But after towing with both, I would not hesitate to recommend the Blue Ox system!
