I don’t know anyone who starts in 1st even with a full load. Maybe some very heavy haul guys.
In a bobtail, I would routinely take off in 4th or even 5th, in a 10 speed.
Another thing to consider is the amount of torque available.
I have on occasion went through every gear without ever needing to accelerate. Did you know that in a semi trucks, bobtailing, in top gear, that idling the engine will still have you doing about 40 to 45mph.
And due to all the torque, it won’t really be lugging the engine either to idle in gear while rolling on flat ground.

Awesome, thanks for the detailed answer!
