The OP also mentioned "easy to use". I don't think the Hensley and it's ilk would fit that bill. I don't even think it would work for my camping style. Though I have no experience with them, I've read enough to feel informed. I often have to hitch and unhitch at sharp angles and on unlevel ground. The Equal-I-zer handles this with ease.
Actually the PullRite hitch would hitch/unhitch even easier with it's 70 degree rotation arc then any other hitch, including the entry level Equalizer that provides zero arc of movement. The driver can watch the ball connect looking out the side window while hitching. It is that easy to hitch/unhitch at an angle.
