My truck had no underhood markings of any kind that I could find during teardown. Not even under the AC/Heater box.

Is there a "bare minimum" that all trucks would have, like the PTB stamps on a '69 Camaro?

Does it vary by plant? Has anyone documented any differences?

There's a real tendency in this hobby for people to just copy other people's markings. People also add new ones they've not seen before so that a lot of vehicles have -every- inspection mark you can imagine. So I don't want to get carried away, but I don't want to miss something as basic as the Camaro PTB stamps and have it be conspicuous by its absence!
