I think fatigue failures are mainly due to lots of changes in load rather than the load in itself. As the Tesla truck won't change gear, it would see less frequent changes in load.
Four motors driving each rear wheel directly and independently will further lessen the strain on the frame compared to one big frame mounted engine and gearbox.
