What do you want to know...Equal-i-zer brand hitch is widely used and well proven. It has been around a long time. It incorporates both weight distribution and sway control (basically friction).
My wife hated ours because it was so noisy...it pops, snaps, creaks and screeches.
Good hitch, can't really go wrong with one once it's set up correctly.
Also look at Reece Dual Cam and Blue Ox Sway Pro.
