Stopped in to the local dealer and they had a sale going on. $35,000. for a 3500 diesel 6 speed. Seems like a pretty good deal since I spent $32,000. on my 01. Problem is my 01 only has 100,000 mi. and is in new condition and is paid for. I noticed that the 3500's sit quite a bit higher than the 2500's. Different looking rear springs too. What's the difference?
