Has anyone considered blocking off part of the grill? I know that cars will do this for aerodynamics, at the expense of cooling capacity. My understanding is that our cooling system is more than efficient enough. After peering into the grill, i took notice of the location of the transmission cooler and the A/c condensor. I think these will remain sufficiently cool as well if one were to block off the top and bottom rows. so, my question is, would this produce a significant change in the aerodynamics?
Thanks,
Dan

If your is like mine, you could block off 40% of the grille area and not effect cooling at all.

Ok, but would it affect the aerodynamics of the truck?
This sounds like it's something you've tried, but i cant find a thread on it.
If you already know, or could estimate it, how would it affect the Cd?

I haven't tried a grille block yet, but its on my "to do" list. The back and sides are more important than the front.
