Oh, and it is very easy to convert pretty much any generator from gasoline to natural gas or propane. It costs between $150 and $400 depending on your engine, who you buy your kit from and how far from the meter you place your generator. If you don't already have a T and valve for your BBQ you will also have to add that as well.
To convert ours I bought a regulator, some hose and fittings and printed a bolt on venturi of my own design on our 3D printer for the carburetor on our generator and use a motorcycle air filter on that. But I am not sure that it was worth the extra effort to save a few bucks.
