slowmover, that's a good idea about using the hour meter on the in-cab display. Next tank I'll try to reset that. Maybe I'll even do the math to adjust for this tank.

ExplodingDinosaurs, if you're not going to do anything enginewise, you're pretty much left with aero mods, IMO. Your DPF prevents you from doing much on the diving style front, because it requires high exhaust temps, which pretty much means high rpms and little idling. Therefore, you can't keep your rpms low or do much coasting (which can give you a BUNCH of mpg's. You can still look into an aero-cap, a grill block, fender skirts, belly pan, etc. I'm currently working on a aero-cap. If you have a short bed and mine works well, I'll post the plans when I'm done.
