No expert, but it always made more sense to change the oil after storage. Almost all of the "old" oil (which after 1-3k miles is hardly "old") is basically just sitting in the bottom of the oil pan. Why would it hurt anything? Even when you change the oil, the "old" oil is what's lining the cylinder walls (and everything else), not the fresh stuff you just dumped in, at least until you start it up. Also, I would think that the possibility of condensation would indicate that it would make more sense to change the oil after storage.
