my 01 ran 1800-1900 at 70 it was 4wd would never get under 17-18 mpg no matter how fast you drove it. most of the time was in the 20-21 mpg range. saw about 23-24 mpg once on the highway. i dont see that your lugging it like mentioned. most v8s dont lug until there under 1500 rpm. my dads 4.3 s10 was the same it was 67 at 1900.
