An outdoor cooking cooker having a lid biased towards an open position by a torsional spring and able to remain partially open at a plurality of partially open positions by increased friction against the lid along a pivot. The outdoor cooking cooker may also include a vertical lifting device for lifting a single rack or multiple racks out from the outdoor cooking cooker and a device for coupling the racks together. The outdoor cooking device can include a firebox that is double-walled and may be mounted upon a trailer for easier transportation between locations. A flexible peripheral seal damps sound and seals against leakage when the lid is moved to a closed position.
