I too am unqualified to give a valid response, but in theory, if you can hold that 10 speed transmission in any gear you want, I’d see no reason to not have the “long legged” rear end. For example, if with the 3.73 you found yourself on a stretch of road where the transmission might “hunt” one would think that in the tow/haul mode, the TCM would simply choose to keep it in a lower gear, or by taking manual control, you could simply choose a lower gear. Again this is just theory……

I would choose the 4.10 for a dedicated tow mule, dump truck body, heavy camper or other heavy hauling application, but then again the anticipated weight of your camper is 2,000lbs which is approx equivalent to a ton.
