So, I am having hard-time believing a 5yr old 3/4 ton 4x4 truck would get that...

I know by getting an enhanced air filtration system I can add another 2/3mpg but haven't seriously looked into it yet. I think it costs like $250-$300 but a worthy investment since I heard it -supposedly- increases car's power another 5 to 10 horsepowers. Getting a hard tonneau cover (snugtop $800) couple of years back, did improve the truck's aerodynamics which increased the mpg a little bit but more importantly it rides much smoother at higher speeds...

AHAHAH!!! horsepowerS!!! Plural??!!?? Wow...

You can easily squeeze more mileage out of diesel trucks of any sort, increased filtration, improved exhaust, and a tuner are the top 3 best ways to do it. And with it being older, everything is broke in so it runs easier.
