Abstract: A vehicle carrier apparatus, that is adapted to be mounted on a first side wall and a second side wall of a transporter vehicle, includes a framework assembly that is screw clamped onto the side walls. The framework assembly has riser assemblies which support a transported-vehicle support assembly. A fence assembly may be connected to one side of the framework assembly. A retractable ramp assembly is supported by the framework assembly between the transported-vehicle support assembly and the side walls of the transported vehicle. The retractable ramp assembly includes a first ramp portion supported by the framework assembly and includes a second ramp portion supported by the first ramp portion. Both the first ramp portion and the second ramp portion are adapted to be slid horizontally away from the framework assembly.
