Introduced in 1978, the ER was produced through the 1980s with relatively few detail changes. In 1984, the headlights and front turn signals were switched from round to rectangular units. In 1991, the driver's compartment was redesigned, with a much larger windshield. During the late 1990s, this model was distinguished from MVP-series ERs by its optional black plastic headlight trim.
