I'm looking at a 2004 3500 Dually Cummins. Found great deal on it. Crew Cab, Long Bed, Dually, 6 speed, 4x4, Leather Laramie Loaded! Miles are a bit high (250k) but its clean and asking price of $12,500 OBO is too good to pass up without looking.
If it checks out, front end, motor, tranny axles, etc... that is a great deal....

It is a bit more than I wanted to "spend" (Finance) but for the price it's hard to pass up. I could resell it in a year and still at least break even, if not make some profit. I've watched the Cummins truck market for years around here, and any other truck like that is $18K + at least. It's only an hour away so I might take a quick trip up there tomorrow afternoon and check it out.
250K miles is a lot and those miles include wear and tear on the shocks, brakes, rotors, ball joints and tie rods, etc. an the likelihood of expensive repairs to injectors and other parts. 2003 was a major model change year for Dodge trucks. Most of the problems with their turbodiesel trucks has been with the drive system (all years) and the fuel system (2007-2010 trucks) and with major engine problems much more likely with the 2007 and 2008 year trucks. The 2007 model year turbodiesels were generally lemons all the way around with problems with the engines, transmissions, drive train, fuel system, and the electrical system.
A lot easier to find a camper that will fit a long bed truck. Main difference is that the campers built for a long bed will have the center of gravity further back from the cab so it sits over the rear axle. A camper built for a long bed will typically be heavier by 500 lbs. and often by much more than that.
