Explain the physics for us when both options are well within tow ratings.

If you have a 4x4 and are having difficulty backing into a site...drop it into 4-Lo and you will have far more torque than the 4.30 gives in 2-High. But really, that's a pretty rare issue. Most people towing 15k 5th wheels aren't backing up 20deg inclines.
