I'm a retired electrical contractor, if you have natural gas , @ your house-its a big plus, otherwise go with propane--gasoline in an un injected engine is hit or miss for reliability--kohler is very reliable--, all you really should care about is enough power for a/c, refrigerator and lighting--if you want to not get a real big unit get a window a/c unit for a bedroom, easy in and out and will function with a small portable geneset, however; gasoline may not be available during a prolonged power outage==have enough fuel for 10 days
