This is a 4.7 L. V-8, 5-speed automatic with 3.55 rear gears. It is the Sport Plus package 26C, and aditional options include:Heavy Duty Service Group, Trailer Towing Package, Infinity sound syatem w/ CD & cassette, sliding rear window, and power heated mirrors. Sticker MSRP was $24,285. Purchased in April 2004 at Moser Dodge in Cincinnati, Ohio, who went out of business that August. I traveled a lot and by the end of July the truck had over 9,000 miles on it already! It went to Cape Cod, back through upstate New York, down through Virginia, the Carolinas,Florida, and on to Texas before coming back to Ohio through another half dozen states. I added an aluminum air intake with conical filter, which contributes to the powerful sound of the vehicle. Also added an R/T decal to the tailgate, tailgate lock, fiberglass topper, custom tailights, clear front turn signal/parking lenses, and customized the bed area with additional wiring for an auxiliary battery and storage space. Also added 265/70/16 Winterforce tires that really grip. If I had ordered the truck I would have added the power seat and a limited-slip differential.
