The first-generation Ram trucks and vans introduced in 1981 featured a Ram hood ornament first used on Dodge vehicles from 1932 to 1954. Not all of the first-generation trucks have this ornament and is most commonly seen on four-wheel-drive models. Dodge kept the previous generation's model designations: "D" or Ram indicated two-wheel drive while "W" or Power Ram indicated four-wheel drive. Just like Ford, Dodge used 150 to indicate a half-ton truck, 250 for a three-quarter-ton truck, and 350 for a one-ton truck. The truck models were offered in standard cab, "Club" extended cab, and crew cab configurations. They also were offered along with 6. 5 ft (2. 0 m) and 8 ft (2. 4 m) bed lengths and "Utiline" and "Sweptline" styled boxes along with standard boxes. Externally, the first-generation Rams were facelifted versions of the previous generation Dodge D-Series pickups introduced in 1972. The new model introduced larger wraparound tail lamps, dual rectangular headlamps, and squared-off body lines. Engine choices were pared down to the 225 Slant-6 and 318 and 360 V8s. The interior was updated and included a new bench seat and a completely new dashboard and instrument cluster with an optional three-pod design - a speedometer in the center, with the two side pods containing an ammeter on the top left, a temperature gauge bottom left, a fuel gauge on the top right and an oil pressure gauge bottom right. Models without the full gauge package had only indicator lights in the place of the temperature and oil pressure gauges. Among the options offered on the Ram were front bumper guards, a sliding rear cab window, air-conditioning, cruise control, tilt steering column, power door locks and windows, AM/FM stereo with cassette tape player, styled road wheels, aluminum turbine-style mag wheels, special paint and stripe packages, two-tone paint, and a plow package for four-wheel-drive models (referred to as the Sno Commander).
