Abstract
Abstract A simple, inexpensive ramp and cargo system is described that is easily mounted to a standard trailer hitch socket of a vehicle with a rear door or hatch, including a minivan. The ramp can be used to load small sized wheeled vehicles, including occupied wheelchairs, into the interior of the vehicle. The ramp and cargo system is carried outside the vehicle and does not decrease the interior space of the vehicle. The ramp and cargo system can optionally serve as a deck attached to the rear of the vehicle to provide additional cargo space. This external deck can be expanded and partially enclosed with two platform pieces and sidewalls. The ramp and cargo system is inexpensive, light-weight, easy to install and remove, and easy to deploy as a ramp.
