Coming down a twisty mountain road as passenger in a heavily loaded
5-ton I watched the tach hit 5000 RPM, twice the redline. I suppose
the engine can survive whatever full scale on the tach is, right?

Depends. One thing if you are using the engine as a large
air-compressor "brake, another thing if you are trying to get power
out of it at that RPM.
Your Mileage (engine hours) will vary

No matter, we had a rich Uncle who would pay for what we broke,
usually without asking questions.

There is that. Not to mention buying the AV gas for your plane
(but that is a more .. specialized group, those active members of
Uncle Sam's Flying Club.)
