A vehicle cargo carrier including a cargo platform for placement of cargo thereon, the platform supported by a lower support base affixed atop a vehicle which allows the platform to be manually drawn laterally outward and then to be pivoted from generally horizontal into a tilt along side the vehicle for easier reach. Low-friction plastic strips mounted on surfaces of the cargo carrier provide low friction sliding of the platform on the support base. Low-friction lateral guidance plastic strips extending into the area of pivot studs maintain lateral alignment when the cargo platform is tilted relative to the support base. The pivot studs on which the platform tilts are intermediately or non-edgewardly positioned of the platform to allow placement of cargo on the cargo platform on each side of the pivotal axis so that the weight of the cargo is distributed to aid the user in tilting the platform back toward horizontal. Tilt-stops, preferably adjustable, are applied between the ends of the support base and the underside of the platform to prevent the tilted platform from striking the vehicle and to set a predetermined maximum tilt angle. Manually de-latchable latches are mounted on the cargo carrier to engage between the platform and support base for holding the platform in a retracted position allowing driving of the vehicle.
