I would like to ne able to make an educated decision as to what I need to do next to my truck to reach my ultimate goal of 25 mpg on the highway at 65 mph.

Hope you'll search around on other threads for more info. But a 4WD is hard put to reach above 20-mpg very far due to the real increase in rolling resistance (drivetrain) and aero pressure increases (vehicle height).

You might consider the Tone Ring Mod as a cheaper alternative to the Smarty Jr.

The MICHELIN LTX A/S is a better LRR tire than the LTX M/S. (There's a retired engineer in Alberta running oilfield hotshot in a 2WD; he runs NOKIAN HAKKEPELITA in the winter, and an LRR in summer; over 20 mpg on his 2006).
