I have a 2010 on order
and have ordered a Trailer Saver hitch from Hensley. The TS mounts on the Reese system and according to Hensley I needed special brackets for the 2010.
I ordered them with the hitch (from Hensley, $200) so unless they're working me over you'll need brackets. I'm trusting Hensley to know what's required.
They wanted to know If I was getting a long bed dually (yes) so that may be a factor as well. I don't know why this would matter. It could have just been a curiosity question.
BTW they were offering a special of $200 dollars off on the hitch so it all came out (of my pockets) in the wash.
