Marketing was explained to me many years ago this way: “ the art of convincing some one to buy a product that they don’t need but got to have by the time we get to the end of the pitch.“ Banks is a master salesman.
Not disagreeing, just pointing out that the gains/positives of many products are slim with no practical value to the average user.I mean that is the standard in selling. You first describe the problem, let people know the scope and scale of the issue, then you present the solution.
That said, I don't see data disproving his arguments, which leads me to think they hold some amount of water.

My 2nd gen hasn’t complained either. As we all know, fluid changes and quality fluids are key.I towed heavy (over the GCWR) for 16 years with my 3rd gen and that 11.5" 4.10 gear set looked as good as new both times I had the stock diff cover off and replaced fluids (30K & 60K).
I do see some merit in the fluid dynamics of using a cover that contours the ring gear and keeps the diff fluid from foaming, but lots of folks have been running flat back covers for a lot of miles with no reported ill affects.
