Improving Gas Mileage

I am wondering what I things I can do to improve my gas mileage while towing?

As others have said, speed has a greater impact on fuel economy than any other factor by far.

Aerodynamic drag goes up with the square of speed. Required horsepower goes up with the cube of speed. In other words, if you double your speed, you'll create 2*2=4 times the drag and need 2*2*2=8 times as much power.

In real-world terms, slowing down from 70 to 55 is 76% as fast. It creates only 62% as much drag, and requires only 48% as much power.
