Pictures? I have pictures. Of course, I don' t do a great job of labeling them.
The first shows where I put Airtabs on the roof of my sleeper (3/10 mpg savings). The second pic shows the Airtabs on the fenders and the back of the West Coast mirrors. The third and fourth pics show a fender in snow and ice.
The picture I didn't get ('cause I wasn't up for climbing up on a slippery truck) was of the ice buildup on the sleeper Airtabs and no snow or ice until right at the top of the chrome curve on the box.
