I previously owned an 01 Ranger XLT 4x4 with the 4.0 and 4.10 axle ratio with automatic transmission. I am currently looking to trade my car on a 2010-2011 Ranger XLT 4x4 with the 3.73 rear end. What kind of highway MPG is everybody getting with these? I know my old 4.10 rearend would see 17-19 mpg highway, any better for the 3.73 rearend? Any input would be great! I miss my Ranger!
