Thanks, everybody.

Future additions could include:

* Air Curtains both at front and at rear corners (my roof wing might have a little curtain effect to it FYI). Cab-over racing trucks in Europe would be a front corner example. I did a proposal for my rear cab corners using quarter round PVC tube but never followed through. This might be best categorized as experimental things yet to be validated.
What is nice about the document as it stands is that the modifications covered are fairly pick-up truck specific.
Whereas the additional topics proposed above may cover more vehicle types, both an advantage and disadvantage depending on how concise you like your documents.

I might do a couple more articles in the future, but it will be hard to organize. I think there will have to be separate articles for sedans/notchbacks/coupes and hatch/wagons. Front end mods can be shared among body styles, but the rear ends would be different. Combined, they'd make up an extremely long article.
One thing holding me back is that without the graph of modifications as a guide, it's hard to say how much certain mods would help. If I knew of such a graph, I'd be much more likely to try it.
Look at this- it's an actual scholarly paper about drag reduction, but they start out with a freaking cartoon car! It can be challenging to find trustworthy information. I'll bet Hucho has some good stuff... if I wanted to spend three weeks combing through the book for a single blog post.
Air curtains... yeah, I haven't heard of anyone successfully DIY'ing those onto their car. I only want to present mods which have a measured benefit.
The EM "65+ Efficiency Mods" is a good start, but (no offense, Darin) is really vague and sometimes misleading. For instance, no one removes their door handles for drag reduction, although that is listed with a 1 out of 3 impact on fuel consumption. I personally would not even mention that.

My FE was terrible, and one variable was the state of tune. I had some more work done in MN, so it's hard to say if the tonneau worked or not.
Tuft testing just told me that the air is indeed hitting the tonneau. Aerohead surmised that it's seeing some big longitudinal vortexes from the cab.
