'Pure' gasoline, as it is more commonly known, can go stale just as easily as the more common E-10.  In either case, the biggest enemy of storing gasoline is improperly sealed containers.  In a completely sealed container, regular E-10 gasoline will store for at least a year with no problems; I've done it myself.  Never, ever vent a gasoline container unless you are actually using the gasoline at that time.

Pure gasoline does seem to run better in 2 cycle engines such as those found in most trimmers, chain saws, etc., but it will still go stale.

If you happen to have stale gasoline, you can mix it up to 50/50 with fresh gasoline and burn it with no problems.

And regarding a propane conversion for a generator, I honestly cannot see much reason to do so in an RV context.  A five gallon gas can has more energy for the generator than does a 20# propane tank, and the former is far cheaper and easier to move around.  There is also a 10% loss of power when running a gasoline generator on propane, so that 3,100 watt generator would become a 2,790 watt generator.
