I am on about my 4 or 5th gas motor GMC truck now and have had mixed results. The truck I own now is a 1999 half ton four wheel drive with about 60k miles. The rear end has positrack and I am getting some noise back there....have tried changing the fluid helped for awhile but its back. The anti-lock break system gave out and now I drive it without ABS as it's $600 to have it fixed and not that impt to me. The tail-gate will sometimes not stay closed....loud bang driving down the road and scares the crap out of ya. Lately the "service 4wd" light has been coming on and I have been told its a sensor as I still have 4wd. The electric window on the right side goes up real slow on cold mornings but still works and has been this way for three years. So I have had "ok" luck with the truck..not great. GMC's I owned before this one ranged from incredibly good to not good at all.

I know you are interested in the Diesel and the only help I can give you there is a guy I met during archery season that owned one. He told me he had almost 100k miles on it, no problems and incredible power.
