Well inspections are done by grunts like sith troopers and stormtroopers, so if your story is basically stowed away on a freighter, cloaked himself then jumped off, that's cool. the minor base is fine too, just so long as it's isolated to this rp and has no other purposes.
It varies on several factors and what your own character is capable of. It's because of this that we usually have the people RPing it out, you basically have to avoid detection during the ship's inspection, which you've stowed away on. If you could explain how he could get in, I could weigh in on it.
