The Curt adjustable hitch design has a simple, clean look to it and is easy to adjust. The included rubber damper to reduce clatter was an unexpected bonus.

I am impressed with the product. I hope more attachment options are made for this set up. Works great pulling 16,000 pound 34 foot cargo trailer.

Haven't used it yet, but it appears to be well made. Over all fit and finish is top notch.
