2004 Dodge Ram Commercial

 In 1998, Dodge introduced the 4-door Quad Cab, which used smaller clamshell doors directly behind the main doors. This was the first extended cab pickup to have four doors. (The 2-door Club Cab remained available through 2002.) Other changes for 1998 included new rounded black plastic side view mirrors, new plastic fold-out towing mirrors, a revised interior, dual airbags, a chime replacing the buzzer for seat belts/door ajar/headlights, and a digital odometer. The OBD-II system was also standard, with a computer port near the driver's-side footwell and a code-checking system via the new digital odometer readout.
