I have a story about that particular wind tunnel test: I was against trying that combination because I did not think it looked advantageous on CFD simulations. This was an early version of FLUENT - the pickup contour basically looked like lego blocks. I thought I could read the tea leaves just by looking at the plots of the velocity vectors to see how big the eddy was that filled the bed region. I was very naive about the limitations of CFD in regards to getting accurate results for separated flows (at least in those days). Fortunately, one of the other guys on the team found an 1/8" thick piece of wood, and quickly cut it into the right shape to go over the last third or fourth of the bed of the 1/5 scale model. My reaction was 'oh what the hell, go ahead and tape it on, it will only take about five minutes'.

That's funny! What a small world! Tim and Pat Nixon gave me a copy of the paper based on your classes research that they presented at SAE in 1988.I think Dr.Maxwell and Pat made the Dallas Truck Show,trying to educate truck owners.Never saw anyone run the mods.What a shame!---------- I'll have to personally thank you for the "aeroshell" depicted in the paper,as I've enjoyed them for a decade now!------ You the man!!!! Thanks for all that,Phil.
