Aeromodding how? Other than the mirrors I'm not sure theres a lot of improvement up front.
I know I could remove the roof rack, but with the crossbars out I dont feel its in the way too much.
I'm also now considering a kamm of some sort too.
But it would seem that the 38 mpg was no fluke. I made an identical trip in very similar conditions and got 37. Might have been more, but once again the pump shut off and I Felt like it needed more gas, but it simply didnt. It might have been closer to 40 really.
