I have 1996 4x4 CC 5 speed getting a paint job, but I have also been looking at used 3500 4x4 quad cab duallies. I have found some nice looking trucks but it seems even the nicer trucks have 100K + miles on them and the owners are wanting more than top dollars. For example I found a 2004 quad 4x4 6speed dually with 120k miles and the prices is $22k. Is this too much coin for a 2004. What would you consider to be too many miles for a used truck?
