[COcyclist]

cons, nice work on your aero mods. I live over a mile above sea level and I do believe it helps with highway mpg but you are doing something right too with your mods. Bicycle racers go to Mexico City for their high altitude velodrome (The hour record for bicycles is the record for the longest distance cycled in one hour on a bicycle. It is one of the most prestigious in cycling. Hour-record attempts are made in a velodrome, frequently at high altitude for the aerodynamic benefit of thinner air.- from Wikipedia) You seem to be getting some good results from your full boat-tail even with the square corners. Ingenious design with the hinge for tailgate access. I hope you can talk your buddy with the TDI Golf to start a build thread too. The photos in your web album are interesting.
