I've never heard of a 17,000 lbs rated drawbar/ball mount that was not of the configuration for mounting a weight distribution system head. So I learned something new today. And is it a 1-1/2 square bar with an adapter? And it's at the right height for the trailer to tow level on a 3500 truck? This all just leaves me scratching my head. Why not go with the traditional setup even if not using the WD bars? You can even get longer drawbars when going that way.
