HiAnyone have the new 2013 with the increased horse power and the new tranny? 385 hp @ 2,800 rpm 850 lb-ft @ 1,600 rpm (Aisin AS69RC trans)Also, I do not do very much towing at all. I normally always run empty etc. What would the best rear end gears should I get to maximize my mpg?:cookoo:

Its kinda hit and miss, some guys get 18+ some get 14. Biggest thing to change mileage is to delete emissions.

Mileage?  BAD haha

Right now in our Ontario winter, 20-21 L per 100 Kms.  OUCH!!!

You're gonna hate me, but why buy a big truck with a huge diesel to drive around empty and then ask for good mpg? Why not just get something like crv or Subaru if you need 4wd and decent mpg for awd. I know truck are cool but I just don't get it.

Here's a spreadsheet I made a while back to compare transmissions.  But it should work to give you an idea of which rear end to run.
