After seeing what Piwoslaw, Wyatt, Darin and others have done, I am wondering if I can create something similar for my Dodge RAM QC. Since I swapped the tonneau cover for a topper, I have noticed FE has dropped. I figure a kammback or boattail (boy would THAT be long....) would help drop the drag. Could I take the same basic picture here and apply it to my truck, or do I need to go to that extreme?
Sorry about the hi-jack. Dave

I agree with Weather Spotter that a longer kamm-back would be better, but I also think that if you get the angles right, it should still be a net benefit. I think that aerohead had a table of "diminishing returns" of a boat-tail. Obviously a full boat-tail would be best, but pragmatic concerns make it necessary for ecomodders to figure out how far they want to go.
But I'll let the real aero-experts chime in.
