I have no idea. a truck like that isn't gonna notice much from small aero changes. (such terrible aero to start with and a big engine to ignore it, even the v6) 1/2 mpg variation in one tank is well below most peoples standard deviation.

1/2mpg when you're starting so low is actually a pretty chunky gain, and I doubt merely folding a mirror in would cause that.
