What would you gain? Fuel economy wouldn’t be significantly better at highway speeds where motorhomes spend most of their time. The 7.3L V8 should be a simpler engine and more durable too.
It would not completely surprise me if in the future Ford made a 6-cylinder version of the 7.3L V8, which would be around 5.47L in displacement, but I doubt that will happen. A modern large-displacement pushrod inline-6 would be sweet, but it would be too long even for truck applications. One of the best Ford truck engines ever was the 300 cubic inch, 4.9L, inline-6.
