Phil can correct me if I'm wrong, but when he said his cold weather aero enhancements didn't really "show up" at the pump until the return of good weather, I believe he was referring to his "previous best" (warm weather) MPG performance, not strictly a before/after comparison in cold conditions.
All else being equal, your absolute MPG will also be higher when the warmer weather returns, but the relative improvement of aerocap vs. open bed should be about the same (at the same testing speed).

Darin,that's it.The cold weather was "suppressing" the overall efficiency of the truck,and influencing the mod I had added in the "cold".
And I did not attempt to do A-B-A tests in the cold,as the bellypan would literally take days to remove and re-install,so all the data got caught within the "creep" of temps.
If Silverado is comparing his aero cap mpg in the winter to a 17+mpg summer baseline I suspect that the numbers will improve with the weather.
