Fuel Saving Tips
Always leave your tailgate up if you have a pickup truck without a cap on the bed. When the tailgate is down, the wind from the roof comes down and catches the top surface area of the tailgate and causes too much downforce, greatley reducing your MPG. If your tailgate will not stay up, then take it off.
