21.5 is a great start. For comparison my 97 1500 5.7 auto burb was able to get 18 to 19 on the highway. I have topped 20 mpg a few times with my 2500 98 dodge ram diesel with the 5 sp ( same transmission your using nv 4500). I press the skinny pedal too hard to post good numbers though. With aero mods, I won't be surprised to see you in the 30s.
