northwest missouri
Have an '08 2500 w 6.0 & 6 spd GM - lots of power, fuel mileage finally getting up to 13-14 range & a little better for strictly hwy use after 15k, our 2000 ford w v-10 has the power and can get close to GM for mileage on hwy but really sucks at general farm use milage, more like 8 mpg.
