I currently own a 2003 2500 HD Chevy 4x4 with a 6.0 and my milage at best running empty on the highway is about 14. Not good. The truck does pull pretty good. I have heard the 5.7 hemi with the new 6 spd tranny will run 20-21 on the highway at 390 HP and 400 Fp of torque. I am not very impressed with the new Chevy and I am a lifelong Chevy guy. The 2500 HD 4x4 has only 9 inches of ground clearance??


If you find yourself in a hole....quit digging
