"I averaged 10 mpg with the deflector raised. Before I installed it, I averaged about 8 1/2 mpg."

Comment: It was easy and quick to install at the rear of my F-250 truck cap. I used it to deflect air over a 12 foot high by 8 1/2 foot wide travel trailer. Most of the 4500 miles driven with the trailer behind me were at speeds of 55 mph to 70 mph. I averaged 10 mpg with the deflector raised. Before I installed it, I averaged about 8 1/2 mpg, both in mountains and flat land.

"I was getting about 9.5 mpg however, after installing your wind deflector, it improved to about 11.5 mpg."

Comment: I have a Ford Expedition towing a 32 ft travel trailer. At first, I was getting about 9.5 mpg however, after installing your wind deflector, it improved to about 11.5 mpg. Installation was easy. I just mounted it on top of the factory installed roof rack. The clips fit into a slot on the rack, no modification needed. For extra safety, I added two U bolts.

"On our first trip we got about 2.5 to 3 mpg more."

Comment: I purchased a WD600 wind deflector and found it easy to install. On our first trip we got about 2.5 to 3 miles more per gallon. Very happy with your product.

Comment: The front of the trailer is really easy to clean now that there are no bugs plastered to it. The wind deflector stays clean too. Never did a mileage test. Make sure the support arms are tight and don't vibrate loose or you'll be hoping that the tightening screw and handle blew into the back of the truck and not out onto the road.

"Better than expected."
