Seems to me, that would be even worse- because you would be keeping less of that "pressure pocket" in the bed, AND have a big inefficient spoiler... Seems it would be worse than having the tailgate all the way down, but what do I know.

I used to be one of those tailgate down/off/net in its place guys until I tried some semi-scientific stuff of my own, and found that I had a marginal improvement over all else with the tailgate up *in that specific truck*... It only got about 8 mpg (83 F250) and anything other than gate-up configuration would drop it below 8 mpg a hair. Each config measured over several fill ups (and it had about 55 gallons on board).
