| Buy a neon

| I don't know much about changing rocker ratios, but you could try weight
| reduction if you haven't already. A fiberglass hood is one good way to
| shave at least 10 lbs off a truck. The stock Gen I and Gen II steel
| hoods are massive. A light weight hood will help. And perhaps an
| aftermarket bumper. The stock Gen I and II rear bumpers have edges that
| curl around the corners of the bed - seriously increasing aerodynamic
| tail drag. A roll pan is a light weight alternative. The Gen III trucks
| moved to bumpers that are the same width as the bed, eliminating the
| aerodynamic drag.
|
| A bed cover will also help MPG. An open bed also increases drag. And on
| a more expensive level, I've always toyed with the idea of replacing my
| side mirrors with flush fitting cameras with video displays in the cab.
| But thats a mod that would not be as easy - or as cheap up front. Also
| the fuel economy savings would take a while to offset the cost of side
| cameras.

Other ways to increase mileage:
- - Lower the truck
- - Different tires/run slightly higher pressures
- - Drive slower
