I was surprised when I looked up your generator to see they claim that it will run on a 20lb tank with the included hose. If I were you I would have to test that and if it works well then keep the gas tank empty and just run on propane. If you have other OPE you will have gas around just in case but with propane you dont have to worry about bad gas or carb deposits and its still portable. When the propane guys get you a hookup to the big tank you will have access to plenty of fuel for emergency backup and no worrys about draining anything. You still need to fog the cylinder and close up the engine when storing long term but not having to mess with gasoline is a huge convenience.
