There are no other brands comparable to the Pullrite SuperGlide. It's in a class by itself. If I had to tow a 5er with a shorty pickup, I'd insist on a SuperGlide hitch.
Pullrite sells a "B&W adaptor for SuperGlide". Instead of the standard "SuperRail" mounting kit for the SuperGlide hitch, you would install the B&W adaptor for SuperGlide mounting kit. The B&W adaptor costs about $150 more than the SuperRail mounting kit.
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.
