Buying a used 2018 X15

It’s not that I don’t want to hear it, I’m just trying to understand. I’m here to learn, I don’t think I know everything, quite the opposite.

That was a good explanation. So what gears would you suggest to be optimal with a direct drive transmission? I run at 57-63mph, lots of steep hills but I run light, around typically only 40,000lbs gross. I just would have assumed that the final drive being equal to a 0.73 18th gear and 3.73’s would result in the same performance since it is equal mathematically.

I don’t plan to turn the truck up, I expect it to feel sluggish when I’m used to 500+ hp and 1850 torque. I haul light so I don’t need big pulling power.
