Is this normal or are we just darned Lucky?

I think some of it is expectations too. Whenever the littlest thing broke on our old toy hauler, we would freak out, because it was brand new and nothing should break, right? But, we've learned that generally, that's just not how it works with RVs. It probably should, but it doesn't. It's a rolling home, things are bound to come loose, shift, etc. You learn how to fix yourself or be patient and have the dealer do it (which is why IMO, it's important to find a good dealer).
