An e-mail I received back on May 9 from B&W.
Thank you for your inquiry. At this time, we do not have a hitch released for the 2013 Dodge 1 ton trucks. We are in the process of designing a hitch, but do not have a good ETA for it its release. Please keep an eye on our website, www.turnoverball.com for the latest information on our newest hitch releases.
Not positive as I haven't checked their site in a while but I'm pretty certain the old turn over ball and hitch won't work with the prep package trucks.
Shoot them a e-mail, they respond quickly.
