I just got mine this year. I found it on CL for $75. It is adj.
I used to get around 6.5 mpg so I figured any little bit would help! Well On our first trip I got 8.5 mpg!!!! I had to recheck my math and the miles. It was for real. The only other difference was new tires on my X (I went from BFG A/T to a more hwy friendly tire), but even with that my mileage without the wing was similar. I even rechecked on the way home and again it was 8.3! And then on our Myrtle Beach trip I averaged 7.9mpg with the mountains I went through out east! By my math I saved approx. $200 on that trip alone!
I also noticed the truck doesn't work as hard to hold speed. It use to kick out of O/D on the slightest hill or headwind! Now it just keeps on pulling until I'm really into the throttle. The key is having the deflector as close to the trailer as possible and at the right angle.
For me, I see excellent results from it's use!
