I just bought an 04 Ram 3500 QC 4X4 SLT DRW and it's my first diesel, can anyone give me some advice on the truck that I need to watch out for? The guy I bought it from took GREAT care of it and I got a great deal on it. I basically am saying that I know nothing about diesels and will read any and ALL advice you all have for me. Thanks in advance!!!!!!
