1986-1990 Dodge Power Ram W250 regular cab photographed in New Castle, Pennsylvania. This is a first generation Dodge Ram, which was sold from 1981 through 1993 as a renamed version of the Dodge D series. The "Power" prefix was used for 4-wheel drive versions of the first generation Ram. This one appears to be a base, possibly fleet-spec model, given that it's in use as a park ranger vehicle.
