Andersen Trailer Hitch

I admit that I used pretty graphs and spreadsheets to sell clients or owners on proposals back when I was employed, so I am familiar with the technique. "The computer said it, so it must be true". I am also familiar with the Scientific Method which relies on verifiable facts and figures to reach a conclusion. It is great that people challenge the Andersen hitch. I do, every time I hitch mine up. So far, it has met all expectations.
