[Christ]

Considering the size of the grille opening, I don't think the slightly forward-leaning grille actually would make a difference, other than slightly raising the stagnation point.

Opinion, obviously, but those trucks tend to have enough room under the hood for a small child to stand in there and wrench on it... there is probably more air going through the grille opening than under it, which means that the forward leaning grille is probably a drop in the bucket compared to the grille.
