I have a 2 2nd gen trucks a 94 & 02. I'm kinda lost on what to tell my buddy about the common rail engines and what to look for , whats better and what's not just stuff like that. Pro's and con's i guess is what i'm getting at. I'm going to have him look on here once the thread get's built up a little with some good facts. He's kinda on a budget so the 03-04 is in his range. So reply's about those years would help a lot.. Thanks guys
