With the price of gas these days I know we're all looking for ways to improve our gas mileage, specially with the large engines most of our trucks have. I have come up with a rather clever solution and my last tank of gas resulted in an average of 342 miles per gallon or 5814 Miles on a single tank (17 gallon tank). As you can see in the picture below I have successfully harnessed the power of the wind to aid in powering my Dak down the road. It works pretty good as long as there is a fair amount of wind. I figured I would share this with my economy minded friends.
