The best anti-sway hitch is the ProPride, designed by Jim Hensley to replace his original Hensley Arrow. Second best is the original Hensley Arrow, also designed by Jim Hensley. Those two cost over $2,000 each, and well worth it.
Third best is any of 4 different WD hitches that retail for around $1,000 and can be found at eTrailer.com or Amazon.com for around $600 complete with adjustable shank. These 4 are:
♦ Reese Strait-Line
♦ Husky Centerline
♦ Blue Ox Sway Pro
Don't consider any WD hitch that you find online for less than $500. Pick one of the above, with the right tongue weight capacity.
Grumpy ole man with over 50 years towing experience. Now my heaviest trailer is a 7,000-pound enclosed cargo trailer, RV is a 5,600 pound Skyline Nomad Joey 196S, and my tow vehicle is a 2012 F-150 EcoBoost SuperCrew.
