Where do you look to see what gears are in the rear end? I know that @ 70mph I turn about 2100. I have the 6 speed manual and factory tires.
Ok, i got a question, never really paid any attention because no matter what the fuel mileage sucks but love the truck. I have an 2007.5 with 3.73's in it, I had the dealer print out a list of everything that came on my truck. At 70mph i'm barely running 1800rpm's so what's the deal, hearing people say that are turnning 2100 at 70. I have the 6spd auto, but like I said the print shows I have 3.73's at a whoping 13 to 14 mpg, LOL
