Go to bluechipdiesel.com to read a little on the Bosch VP-44 "injector pump of doom"
The pre 2003s back to 98,5 were real good trucks with this exception.Also the 5 speeds have a bad rep for taking themselves apart if you lug them.
My die hard Guru did all kinds of terrible and wonderful things to his 2002 for many years and recently got a 2006 3500 6 speed, LOVES IT! Says hes getting 25 MPG w/90 horse injectors.Also, conventional wisdom locally says an auto just will not live behind these motors, I advise to not buy an auto at all.
Luck, C

I'm 55 now, no time to waste. Not a week goes by that I don't hear about someone passing on.Let's get out there,smoke some tires,have a beer with a good friend,do what you have always wanted to do.I am pretty sure no one will ever say on their deathbed "gee I'm glad my life was calm and boring"
