"and sometimes even different rear axle ratios. "
The rear axle ratio used should be determined by the torque/horsepower characteristics of the engine involved.
Also the transmission ratios will be included in determining the rear axle ratio.
Thus I would not expect nor should it be required that all of the trucks tested should have the same rear axle ratio. Each truck should use the ratio that best fits the above described issues and the job or hill that will be used.
No argument if the trucks are supplied from the manufacturer to test how fast they can climb a hill. I have watched the Gauntlet test videos and in some cases the testers said that the truck tested was the truck that was available, not necessarily the one that would be provided by the manufacturer as their offering for the fastest up the hill. And, of course, it also depends to some extent on the entry speed for the test. None are tested from a standing stop, all from entering the freeway at least 35 mph. The tests are fun to watch but I put no statistical inference into the findings.
