My latest project was to "fill" the space on the front of the van with a metal sheet. I have been getting 5.61 miles per gallon of fuel. I figured the "hole" in the middle (see BEFORE photo) was catching a lot of air since it had a "roof" over it. I hope I can improve my mileage somewhat by "filling" that space. A piece of 1/8" sheet metal did the trick. Once I get another tank of fuel I should be able to tell if this made any positive difference.
A fairing in the roof of the cab would probably help with fuel mileage so your not pushing wind against the flat surface. Would be nice to have brackets so you could take it off if you did not see a significant increase in mileage.
