hey all! new here and i have to say i'm very impressed with all of the information i've found here! i just purchased a 2002 2500 hd with 91K. it has the 6.0, 4x4 and seems to be very well cared for. my question: what should i look out for and, besides changing all the fluids, what else should i do to it? any help/suggestions would be appriciated! Thanks!
