Now, I'm not a nut for gas mileage. As long as it's decent, I'm ok. But I took a look at my gas mileage from my trip to Texas and back and I averaged 12.5 mpg! I have a tonneau cover and had a couple hundred pounds of stuff in the bed, but I wouldn't think it would be THAT bad! GPS said my average speed was 67 mph over 18 hours and 1200 miles.
Has my lift and everything else I've done to my truck really done that much to my gas mileage?
