How to improve a trucks gas milage? I get 6-8 miles a gallon!!!?

let's face it 27 years ago trucks weren't built for gas mileage, they weren't even built for safety with the fuel tanks outside the fuel rails. with the price of fuel you may want to move to a model year starting with a 2 (2000 or newer) keep the 81 for a toy but not a daily driver. the fuel savings could probably make a good chunk of your payment. probably cut you fuel consumption by almost 2/3.
 
thats a big truck with a big gas engine. get a diesel if u can. if not if u have big tires on it thats going to make it worse for 1. if it hasnt been tuned up new plugs cap wires it will help some. lighten whatever load u have if u r hauling around 1500 pounds of tools all the time loose them. check ur carb make sure ur not burning rich. other then that i cant help ya man.
