I have an '03, the first years 1500 w/ a HEMI and it's been a great truck drivetrain wise. I have 155,000 w/ only a power steering pump failure new, and typical brake changes. However, living in NY w/ the salt, it is rusting away. Holes in the quarter panels, cab corners, and numerous other spots. I'll still buy another Dodge though since it's been a very reliable ride for 10 years.
Probably will get a '06/'07 mega cab diesel,6 speed though for my next one for better mileage when towing.
