I've got 4x4 with 285/75r16 bfg all terrains with 3.31 gears

 

And I got it for about 400 from Clark@autoanything on here

 

Awesome guys, I'll start shopping around. I got the tire inflated and have done everything I can without aftermarket products, and being light on the gas got me 14 highway. Plus I'm not looking to make it fast, since it's only a gas truck, I just want better shift points and fuel economy.
