I am looking at some used 2001 and 2002 2nd gen 3500's. The 50k miles 6 spd HO is going for $26,000 and the 90k miles auto is $19,500. I would like to have the 6spd for the high output motor and longevity of the transmission, but saving $6500 is nice too. I can upgrade the auto later if it gives me trouble. Leaves extra money for the fishing boat I would like to have. What a tough choice. Give me your opinions
