Abstract: A new and improved carrier apparatus for mounting on the roof of a vehicle. The apparatus of the invention includes a housing, magnetic mounts for connecting the housing to the vehicle and for supporting the housing in a horizontal orientation, and a drawer for sliding in and out of the housing. A pivoted connection is provided for connecting the drawer to the housing. The pivoted connection is located between the far end of the drawer and the housing and pivots the far end of the drawer with respect to the housing when the drawer is pulled out from the housing. The pivoted connection permits the drawer to hang down vertically from the horizontally oriented housing when the drawer is pulled out completely from the housing. The drawer includes walls which define a storage space. Partitions are located within the storage space for partitioning the storage space into a plurality of storage subspaces. When the drawer is retained in the horizontally oriented housing, the drawer is in the horizontal storage mode.
