Abstract: A cargo carrier platform for use on the outside of a motor vehicle having a frame mounted trailer hitch receiver includes a rigid platform for mounting the cargo carrier, and a separate bracket for attaching the rigid platform to the frame mounted trailer hitch receiver. The bracket is adapted at the lower end for insertion into the receiver for supporting the cargo carrier platform without attachment to the bumper, frame, or any other surface of the vehicle. At the upper end, a rigid, flat platform is attached to the bracket by way of a swivel mount to support and stabilize the cargo carrier. The bracket and attached platform are shaped to position the cargo carrier over the vehicle's trunk. The attached cargo carrier platform rotates in its mounting bracket to permit access to the vehicle's trunk without the necessity of the removal of the cargo carrier or its contents.
