This is always an interesting experiment and with the current price of fuel important. I added my deflector last November that was made from fiberglass panels around Sleepy's ideas.

Last weekend I got in a fuel test going from home at 8300' over two low passes and down to about 5000' east of Denver and then back. A trip of about 160 miles each way. I had the cruise set at 60mph both ways and of course take it off climbing the passes. Result was 13.3mpg as compared to my long term typical 11.7 at an normal 62mph. I regard that as a great change. Rig ismy 2006 Duramax with monstrous Host Mammoth.
