Not needed. More speed towing is dangerous for many reasons, and you achieve a good speed now. Lugging any engine while pulling a weight not good either. Continual searching for correct gears can't be good. The best overall range for towing with that Cummins is around 1800 RPM so in my opinion not needed.
Most of what you said is an argument FOR more gears.
Lugging is certainly not good for the engine. You need more gears to keep the engine in the ideal RPM range over varying conditions.
This raises the question of what is the definition of lugging and engine? Every vehicle that I own keeps the engine turning as slow as it can while providing the required power, presumably for fuel economy. I frequently force a downshift but I also wonder what the thought process was for the engineers that are designing those drivetrains and what they consider lugging to be.
