I also had a Reese equalizer type hitch. I really didn't need one when I towed a 2-horse bumper pull with my F-250. but when I moved up to a 3-horse SL with dressing room bumper pull I got the equalizer thrown in by the seller. Man, when I tried towing that long trailer without the bar's attached that thing would start wagging my truck at about 50 mph. Put the bars on and it pulled like a dream.
I couldn't tell you what brand I have but I will never tow another trailer without that hitch. WOW! IT is SO much more secure feeling even with a 3/4 ton truck. Being paranoid when we are towing our beloved creatures is not a bad thing.
