My 2005 Ram 3500 Quad Cab dually 4x4 has been nothing short of terrific. The Cummins diesel has more than enough power and torque for everything I need to do, and the 48RE automatic is more willing to downshift. Inside, the premium cloth is very comfortable. The rear seat is sufficient for kids and child seats, and is adequate for adults on short trips. Exterior fit and finish is excellent. The paint (Patriot Blue Pearl) has even coverage, even inside the bed. The sheetmetal cut lines are straight, the doors open and close easily, and all components are tightly mounted. So after 10,000 miles, I have been very satisfied with this truck, and look forward to the next 6-7 years!
