 The Convoy and its predecessors were the larger versions of the LDV Pilot (and its predecessors), all of which were based on the Leyland Sherpa series of vans that was first developed in 1974, sharing some components with even earlier models.In 1984, the "Sherpa" became known as the Freight Rover 200 Series, and gained square black headlamp bezels with round lamps (later replaced by the same rectangular headlamps as on the 300 Series), new black plastic bumpers (replacing the previous chrome with embellishers item), rounder wheel arches, redesigned rear-door hinges, door handles, door shape and repositioned indicators (raised from the rear bumper to the hips on all panelled models thereafter).Alongside the original bodystyle there was a new wide-bodied variant—the 300 Series, available in a choice of three wheelbase lengths.
