Default Mpg?

hey everyone, i am getting pretty bad mileage right now... my average is around 13mpg.. i think that is really low. but then again i do lay into it once an a while.. i'd like if you all could just tell me how "easy" or "hard" you drive your truck, and what kind of mileage you get... and if you have ever actually noticed a big difference in mileage depending on how much you hot rod it.

I tell ya what I wish I had the luck some of these people have they roal more coal than a train and still get 900mpg, I on the other hand drive very conservatively and can maybe average 14-17 in town and 18-20 on the interstate, maybe if i'm luck i'll break that 20+ barrier but i doubt it
