A refuse collection vehicle for loading, compacting, transporting and ejecting refuse materials is disclosed including a hollow refuse storage enclosure having a forward refuse receiving opening, and a rear refuse discharge opening closed by a tailgate. A generally full width charging hopper is located forward of the storage enclosure for receiving refuse from refuse containers, the charging hopper having sidewalls and a floor and being in communication with the storage enclosure. A variable stroke followerless packer-ejector panel mechanism is provided to move refuse materials to the sweep charging hopper, pack the refuse materials into the storage enclosure and fully eject the refuse materials from the storage enclosure. The truck body accommodates one or more container handling devices selected from narrow profile side-loading and front-loading container handling devices or a combination thereof for emptying containers into the charging hopper. A control system is provided for controlling the stroke operation of the packer-ejector panel in relation to the container handling device and eliminate the need for a follower regardless of collection container density.
