Most have already covered all the weak points of these years. Lift pump and or injection pump is a biggy. Even though I don't think I have abused my truck (2002 HO with 6spd manual, 2wd - only 61k miles on it now - owned since new), I still had to do the lift pump @ 40k miles and the injection pump. I am pretty nutso about maintenance. . . so other than that, the truck has been flawless . . . if you are getting to tow, you can't go wrong. Just make sure it is checked out thoroughly. Also can go to the dodge truck forum to see other issues . . .

Good luck

Cheers
