I think that the griddle should come with adapters that allows you to hook up to 5 gallon bottles. I was disappointed at first as the griddle would not light due to low pressure regulator, shutting off fuel flow. It requires a different regulator and adapter. Also need different adapter to hook to our RV, which is the reason we purchased the griddle. One other issue I think the manufacturer could do to make a better product is to already season the cast-iron griddle.
