I'm looking at this truck on the dealer lot crew cab short box. I know the rear axle makes a difference towing but with a truck camper should I pass this truck up and wait or order a 4.10....I would ...

There's only a small rpm difference between those 2 ratios at equal road speeds, with equal tire diameters and transmissions. I would have to do the math to know for sure, but going by memory I think it's only like 300 rpm.
The greater torque multiplication of the 4.10 is worth more than the slightly lower rpm of the 3.73
This finally helps me understand. But I have a question. I might guess that torque would be in direct proportion to rpm. That the purpose of lower axle ratio is to increase rpm.
If it is only slightly more rpm wouldn't that imply only slightly more torque? Or are there other factors other than engine rpm which contribute to torque?
