Another Truck....
Long time lurker, new poster......
I'm a carpenter, and I use my truck for work. For 3 years I've been driving a '97 Dakota 5.2l 4x4 5spd with a 3" body lift and 33x12.5's...... HORRIBLE on fuel (usually 13-14mpg, never over 15.5 since the lift and tires) and it was time for a change.
A month or so ago I bought a 2000 GMC Sierra 4x4 4.8l auto. I've been getting around 16mpg with it so far, which is a definite improvement over the Dakota, but I'm looking for more (of course!). One tank I had a lot of longer trips at 55-60mph and squeaked out 18.4mpg! With that one tank (29.5 gallon fill ups from the low fuel light) I figured I saved around $35 over driving the Dakota.
Where should I start? Chin spoiler? Lower it? Take off mud flaps?
