I will bet that his point in raising the airfoil is what you see in the last three trailer images I just shared from the post you linked. If you look at the last three trailer designs and imagine the airfoil overlaid upon them, the gap is more or less where it is in the split airfoil that produces the lowest drag. And these are the trailer set-ups that produce the lowest drag estimates. So, as aerohead said, you are on the right track with the baffles and kamm and such.
