They don't change it, they check it.
It's only changed when the check indicates a problem or that the oil has worn out.

Yes, I have "some" idea
Trucks have
- larger sump capacity
- proper oil cooling, better filtration and lubrication system
- different grade, lower viscosity index and higher viscosities than in passenger cars, higher content of goodies like phosporus to protect from wear etc
- different load profile, no 5 minute trips to post office and back with cold engine
(I don't mind if someone wishes to spare miniscule amount of money by avoiding oil changes, it's his/hers property...)
