Chevy makes a gas saver version of their truck that runs a 3.03? (I think) gearing with an airdam and a grille baffle that works ok for general hauling from home depot, but you lose a lot of towing ability. Chevy also makes a hybrid that will get you 20. I don't know enough about the current Ford or Toyota MPG to say anything there.
If you can get 16 to 17 in all around driving, you are doing very well by full sized gas truck standards.
As far as diesels go, a used 5.9 Dodge can get you there. It's not unusual for these to average 19-20 in mixed use with over 20 on the highway. The 6.7 will not get you there.

Thanks for the responses! bigearl, I found an 05 Silverado Z71 extended cab with the 5.3, not sure on gearing. i have heard real good things about the 5.3 and gas mileage and am thinking outside of the 5.9 cummins you mentioned may be my best bet. My big hanguop is my long drive to work (50ish miles 1 way), though it is mostly highway.I may consider the Colorado V8 as a lot of guys with them are claiming 18-20 in mixed driving and I have heard the same for the 08+ Dakotas with the 305 hp 4.7. What to do LOL.
