Reving up the engine to pull off is not necessary
Don't revv up the motor before letting out the clutch to take off. It is a huge sign on your head screaming, "HI! I'M A NEWBY!!" Diesel motors in big trucks have plenty of torque at idle to take off. If you can't you're in too high a gear. You aren't in a mazda. just a note from a driver trainer, take it or leave it.
Don't embarrass yourself.
