• a base;
• a first side wall extending upwardly from the base and having a curved front edge;
• a second side wall extending upwardly from the base and having a curved front edge;
• a flat rear wall extending upwardly from the base and connecting to a rear edge of each of the first and second side walls;
• a first support member attached along the curved front edge of the first side wall, the first support member including a first channel;
• a second support member attached along the curved front edge of the second side wall, the second support member including a second channel;
• and
• a roll-up door having a first cable on a first side edge and a second cable on a second side edge, the door extendible from an open position in which the door is rolled up, to a closed position where the door is at least partially unrolled and the first cable is positioned in the first channel and the second cable is positioned in the second channel.

A method of loading cargo into a cargo container having a curved front end defining a curved plane and a flat vertical rear wall, comprising the steps of:

• loading cargo items against an interior surface of the flat rear wall until the items are loaded to near a ceiling of the container;
• loading additional cargo items into the cargo container until the cargo container is substantially filled with cargo items;
• pulling a roll-up door down along the curved front end of the container;
• maintaining the door in the plane of the curved front end;
• and
• pulling a leading edge of the door down to a position adjacent to a base of the cargo container.

A cargo container, comprising:

• a base;
• a first side wall attached to the base;
• a second side wall attached to the base;
• a front wall attached to the base and attached to a front edge of each of the first and second side walls;
• a substantially vertical first support member attached to a rear edge of the first side wall, the first support member including a first channel;
• a substantially vertical second support member attached to a rear edge of the second side wall, the second support member including a second channel;
• a retractable door positioned between the first and second support members, the door including a cable attached each of two side edges of the retractable door, wherein the first and second channels are each configured to receive one of the cables;
• and
• at least one pivotable lever on each of the first and second support members, wherein each lever is movable from an open position to a closed position in which the lever secures the cable within one of the first and second channels.
