This is just a basic grill that uses a portable green spin on propane cylinder can be purchased at Walmart/target etc. However, I found and purchased the adapters so that you can plug it into most RV or boat propane line connections, eliminating the need for the green, disposable, expensive cylinders, but still works with the regular green disposable containers if necessary. Grill is used a few times more importantly, selling the connections that were difficult to achieve. The connectors in the hose are almost brand. New only used a few times. The grill has been used.
