Abstract: the roof top carrier of the present invention has a roof top platform that moves horizontally between a storage position at the center of the roof of a motor home and an extended position adjacent the side of the motor home. A drop cradle moves vertically out of the roof top platform in its extended position to a lower position at ground level to provide user access to equipment or luggage stored in the roof top carrier. Two separate motors power the horizontal movement and the vertical movement for moving the equipment and luggage from the roof to the lower position at ground level alongside the motor home.
