I also haven't even finished with the second tank, so who knows what it really is at. Qualitatively speaking, the truck feels less encumbered and seems to track more solidly at freeway speeds, so I am pretty sure there is a positive (or negative depending on how you look at it) aero effect.
Use an engine block heater. Year round. Helps with consistency. A requirement for short commute.
