850, So right and he doesn't even know it.

Unbiased wind tunnel testing of the last body style F150 by our friends to the north (see they dont spend all of their time at Tim Hortons and harvesting maple syrup) found the shorter the bed the worse the mileage when the tailgate is left down and ALL pickups lost fuel economy with the tailgate down. Also mesh tailgates were WORSE than even leaving the tailgate down for creating air disturbance and drag.

I would say that mythbusters methodology is usually quite flawed. They quite often do not account for all the variables and have small sample sizes. This is not surprising given that they have no scientific training. I will however applauded them for promoting science and critical thinking.

Meaner than ymeski56
They also don't have huge budgets to do full blown experiments. They do the best they can with what they've got and I trust em most of the time unless I really see where they messed up. But I digress

And to the OP, your truck was new those first two weeks... now it's broken in and gets better mileage. Your experiment is not perfect either. Try with the tailgate up, maybe you'll get 19mpg.
