A lift assembly adapted for use with a vehicle having a substantially horizontal cargo floor and a trailer hitch receiver, the lift assembly including a tongue member having a longitudinal axis and adapted for slidable insertion along the longitudinal axis into the receiver. A frame is attached to the tongue member and includes a pair of four-bar linkages, each of which includes rigid linkage members pivotably attached along substantially parallel pivot axes. Connected to the frame is a platform having a substantially planar load surface that defines a front edge and is substantially horizontally positioned. A first linkage member and the platform are moved together when the tongue member is in the receiver between a lowered state and an elevated state in which the horizontally positioned load surface is generally parallel with the cargo area floor and the load surface front edge is proximate to the cargo area floor. The platform has arcuate movement between the lift assembly lowered and elevated states and generally horizontal movement relative to the cargo bed as the lift assembly is moved toward and out of the elevated state.
