A bed lift system for a vehicle includes a first moving member, a guide member, a second moving member, and a flexible drive member. The first and second moving member are configured to be coupled to a bed. The guide member is configured to be coupled to the vehicle and cooperate with the first moving member to guide vertical movement of the bed. The flexible drive member is coupled to the first moving member and the second moving member. The bed lift system is configured so that raising the first moving member exerts tension on the flexible drive member which raises the second moving member and lowering the first moving member releases tension on the flexible drive member which lowers the second moving member.
