I was also in the buy :new: camp but it all depends on what you happen to come across. I came across a low mileage 2003 Ram 3500 dually 5.9 back in 2006. Since it was a 2 WD it was not moving on the dealer's lot. It had 7,000 miles (14,000 km) on it and had been traded in for a single wheel 2500. I would never have bought a used diesel but I spoke to the previous owner in person and the rest is history. Like someone just posted we do not drive it but maybe 5-6,000 km per so would we have had any better experience with a new 2006 as compared to the'03, no. I must also say that if you want new warranty coverage and don't mind the depreciation go for it. This is my opinion only. I just happened across our truck by accident. I was looking at "new" back then but s*** happens. Good luck with your new truck and be safe out there.
