Nice job especially on the wheel spats! I was going to suggest getting the Silverado OEM dams (GM/Chevrolet is the only manufacturer that currently uses them, across its truck lineup), but those look pretty good.



You might think about a seal between the bed and cab, as Ram has done on the 2019:



(Sorry for the orientation; I don't know how to change it in the Ecomodder album).

If you don't need the ground clearance, think about dropping it as well. You'll improve the drag coefficient both by increasing the length-to-depth ratio by making the truck lower, and increasing the wheel-to-wheel housing volume ratio, which Hucho reports will lower drag and lift by a considerable amount.

Where is the air through the wheel well vents routed? I don't see an exit on the body side. A Magnahelic gauge would be useful for drawing a pressure map of the inside of the well.
