I traded my 01 dually for a 2013 3500 dually automatic. Had a issue with the factory GN hitch, the hitch was fine just that the ball assy is on national backorder. I hade to lathe my own ball assy to fit the MOPAR hitch. Left the dealer with the new truck hitched to my Living quarters GN trailer. Jumped on I-90 an broke the truck in going over the pass. All I can say is WOW. This bone stock truck pulled over the pass just as good as my 04 with LOTS of mods on it. Love the auto trans. . Oo.
