Regarding oil, road trip miles are easy on aircooled engines. You're going 700-1000 miles per day with only one or two cold starts so the oil stays relatively clean. 5k miles is no big deal.

Definitely taking octane booster.
VR1 is en route. As clean as it looks at 3k of beating on it, I'm sure it'll be ok with 5k of mostly freeway.

Thank you. Good info. I ordered 104 branded octane boost. We'll see how it does.

I'm currently running a full tank of VP110 (available on tap locally) and it's good, reliable power, no knocks or anything.
Maybe adjust timing or use a colder spark plug for the trip?
That way you're not fumbling with bottles or worrying about your octane levels when traversing the Rockies and there are no octane boosters available.
Just thinking aloud.

I don't want to make an entire timing map for this trip if I can avoid it.

California (specifically the central valley where its a zillion degrees and 300 ft elevation) is where I'd toss a bottle of octane boost in.

I'm still going to have an ear out just in case.

The seals are something I hadn't considered. That's an excellent point.
Going with VR1 for this trip.
