I realize that maintenance plays a huge roll but I am seeing a lot of trucks for sale with 175k to 200k miles. When I sold our truck it only had 70k on it. I was told that it wasn't even broken in yet. So, at what point should I say, "too many miles"?

I don't think this is specific to an LLY, it's legitimate advice for any vehicle. But most vehicles aren't 5-8k to replace head gaskets on.
The only piece of advice I'd give is watch out for overheat / radiator clogged up on the air side.
I have an LLY and had an overheat problem:

That was the cause, but it's not that easy to check. At this stage I pull it out every 2nd year and take a look.
I did need my head gaskets done and I'm pretty sure this was the cause.
