Question:
On a 2004 GMC 2500HD crew cab with the Alison trans. and duramax! What kind of gas milage is everyone getting, stock. My truck is driven in Las Vegas, NV (temps. average 100 degrees). My fan is on constintly when I drive around town with the a/c on. It seems like the truck has very little power when fan is on. Is all of this normal?
