I have a 500 gallon above ground tank. It's plenty big enough for my generator. But you have to have room for one and depending on local codes that can be a problem. A buddy of mine had his put into the ground. Pretty neat setup. You don't even know it's there.Most people don’t have the room to store that much gasoline. In many places inside storage of that much wouldn’t even be legal. Either way turning over that much gas would be too much work for most. 15% better run times on gasoline may not be worth it when I can store a 500 or 1000 kB propane tank underground indefinitely. The best of both worlds are the dual fuel gasoline/propane generators. Burn what you have. No muss no fuss.
