I want and can purchase a 2005 auto withthe 4. 10 rear fully loaded cummins qc but I just found a 2002 x cab 4x4 cummins manual shift fully loaded slt with 49,000 miles and it's clean. If I purchase the 2002 = no monthly bill. If any of you out there owned one is it worth getting the 2002, are there any problems with it, and can it be slightly lifted. Also can I bomb the engine?.
