Let's do some math, the Ford 10 speed has the following ratios:
Ratio: 4.6957 2.9851 2.1462 1.7690 1.5201 1.2700 1.0000 0.8536 0.6892 0.6357
From Ford's chart, the 7.3 makes above 400 hp from 4800 - 5800 rpm. In the first 6 gears, those rpm correspond to the following speeds, assuming 4.3 diff ratio and 33" tires:
1: 23 - 28 mph
2: 36.7 - 44 mph
3: 51 - 62 mph
4: 62 - 75 mph
5: 72 - 87 mph
6: 86 - 104 mph
With so many gears, there are very few gaps where the engine isn't making close to peak hp. In fact, from 51 mph and above, the engine is always making 400+ hp, at any speed from 51 - 104 mph.
The "lack of torque" of a big displacement gas engine isn't a concern at all with modern transmissions. At any reasonable towing speed, the transmission has a ratio that allow close to peak hp.
