Just so everyone knows...when I did my partial wheel skirts along with my other mods...I got my best MPG last year at almost 35mpg at 65mph. My best before that was 28mpg. My truck is rated at 19mpg.

I'll eventually trim it down to the outline of the wheel well and fab up a separate brackets fer the front and back sides. To lift it fer access to the tire will require the removal of 2 screws and 2 bolts.
