Well I need to howl at the moon a little here. After about 13ish years I'm back driving a cummins. Holy cow did I forget what these are to drive. I've been driving a 2002 7.3 auto for the last couple years. I do love the truck and will keep driving it in rotation with the "new" dodge. The truck is a 2002 24v 6spd. I drove it 4 hours home from Salt Lake City and I was grinning from ear to ear. Just amazing. 80 mph and I got 15 something calculating off just the numbers. Came out to about 16.5 when corrected for the tires. Absolutely wonderful truck to drive.
