Purchase question

I'm seriously considering buying a 2002 Ram Quad Cab 4x4 with the 5.9 with 50k. Is there anything I should look out for? I currently have the vehicle to drive for a day or so. The truck is in immaculate shape and I don't hear any funny noises coming from the tranny, engine or trasfer case. I've never been much of a dodge fan, but the more I drive it the more it grows on me. Any advice you can give me on this situation will be greatly appreciated.

see if they've replaced the cat. There was a recall/federal mandate on them because of failure.

Thanks, I'll check into that today.
