How to increase fuel efficiency

The 5.6-liter V8 makes it a very powerful truck and it's very quick for its size, but the fuel economy estimates are close to 10 MPG. How can you improve on that? Are there any modules worth purchasing to increase MPG?

I am interested in the same. Because of my job, I have to fill up on average twice a week. Looking for any ideas. Thanks.
