Cast iron across all three burner heads gives this 225000 BTU cooker the mass to hold heat under a heavy pot, which matters when a crab boil drops the temperature. Firepower adjusts at each valve, and the regulator monitors propane flow and stops it when an internal or external fault is detected. The frame stands 30 inches tall on detachable legs, so the cooker breaks down flat for a truck bed and reassembles at the campsite in minutes. Powder coating over the cast iron resists water and rust through a season outdoors. The supplied hose measures 0.5 by 51 inches and the regulator is rated to 250 psig. Overall the unit is 34 by 18 inches on top and weighs 33.5 lbs, which two people move without trouble.
