I'm not sure, but with the template overlay it looks like there might not be a good location for a window. I will be keeping an open mind until I actually get to that stage.

How's yours holding up? Any new developments? Any observations?

A few testing updates on mine, so far;

on my calibrated test hill, I have been coasting from 45 mph to a +5mph over what I was getting before the tail( as an example, if I had accelerated to 76 previously, I would have gotten 81, and of course that would be an average),

P&G now works better than DWL+EOC for my commute to work. Every time I tried P&G over the summer, I used .03 to .05 gallons more going to work. After the tail, I'm now getting about .02 gallons better out of P&G.
20.45 mile trip,
summer record of .20 gallons(102.25 mpg),
recently( before tail) around .29 gallons(70.52 mpg),
after tail DWL/EOC at .23 gallons(88.91 mpg),
and after tail P&G .21 gallons(97.38 mpg).
