The swing away tailgate barbeque cooking system allows for a cooking apparatus to be mounted on a vehicle or RV. The unit can swing away from the vehicle on a plane up to approximately 180 degrees. The cooking apparatus can be pivoted into a position that is favorable for cooking. Adjustable leg(s) can be utilized which enable the unit to be much heavier than other swing away units. The adjustable legs also allow the unit to be in a level orientation when on uneven ground. The unit can be disconnected and rolled away from the carry vehicle. The swing away tailgate barbeque cooking system has the dual functionality to be an everyday home cooking device and a mobile cooking unit for camping or tailgating.
