So maybe 2.8-3.5% better mpg on the highway.More the faster you drive.

Darn I was hoping for ~4% but I don't drive nearly fast enough to get that out of my set up.
I'll rock the full cover for this tank and may try going for the half on the next. If its not enough ill add a Kam back to the cab that will bolt to the cover for extra aero, but probably a cab wing for testing. well it is what it is. If the air don't like it, it don't like it.
