A Must needed device! I think that this product should be sold and/or recommended with every trailer sold in The United States! I have had to hook up to trailers (mostly utility or livestock) off and on, for some 20 years. This product eliminates, or nearly eliminates, getting out and checking alignment, and hit-and-miss (mostly miss for me),in hook ups. I build trailers for a living and can truly see the usefulness of the product.
