... er... sorry... I'll turn off smartass mode ;D
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.
