Yes the Hensley hitch is the best on the market as far as I'm concerned, I know the designer and orignal owner Mr. Hensley he has a small shop at Centralia Illinois In southern Illinois and If you call him he will probably be more than happy to answer your question and matter of fact he will probably be the person that answers the phone.

He sold his company a few years back to a large manafacturing company which still uese his name, and if you go onto the Hensley web site you can order a free demo tape that explains how the hitch works.

I should mention however Mr. Hensley still sells that hitch in his store and you can order one right from the inventor if you would like.

The only thing I don't like about it is the price.

Hope this has been of some help to you. Later jim
