Hi yall!! I am new to the diesel world and I hope to get to know real good. I just purchase my Chevy 2500 HD D/A last week. Man, that truck gots some power!:driver:. I have to watch my speed when I driving around town. I have also tried out the 4x4 and was doing pretty good until I ran into some standing water. Then the truck sank, mud was flying, boys were laughing, the boys had a great time. Ended up getting a wrecker to pull me out and the boys loved that even more and wanted me to get stuck again. I told the boys the next time that we do this I will have better tires. The standard on/off road tires from the dealer just don't cut it. So far the family and I have been pretty happy with it. I just hope that the MPG gets better. So far I am averaging 13.5 around town, not towing anything. Is there anything I can do to receive better MPG?
