It does. We run service vans for cleaning that rarely get shut off during their shift. We also have some Silverados used for pickup and delivery services.
I have had the Silverados go over 10k if mostly highway miles.
The service vans all light the OLM at around 4k miles. Engine life in both is nearly indefinite, with the occasional outlier...
