Is hitting the rev limiter really bad for the engine?

That torque figure is impressive, what power/torque does the v8 Scania produce?

The R730 V8 produces 730bhp @1800rpm and 3500nm from 1000-1400rpm - idle is 500rpm, it's bottom end grunt is astounding.

A fuel cut rev limiter does throw an extra issue in the mix as the lack of combustion pressure means you lose quite an effective 'gas damper' for the valves.

I hear this a lot but it isn't true. It is better to red line as when you change up you are in a better power band so even if you lose a little at the top end you are better in the next gear.

You need to plot the tractive effort.

Ie. powerband for each gear, where the effort crosses is where you change gear. Holding onto a gear can result in less wheel torque than changing up earlier.
