The caveat with respect to Ford's limit,is that CdA is CdA,and if you can get the Cd down low enough,then it's the same as a smaller frontal area.
As far as physics goes,the Spirit of EcoModder is identical to a Porsche 928, 968, and Ferrari 348tb at 50-mph as far as Earth is concerned,even though the frontal area of the truck towers over the three sportscars.
We can do the same trick with RVs.
