2016 Ram 2500 with 6.4 hemi and 4.1 towing 12K

spoon059 -I agree. IMHO, the 4.10 ratio should be ordered far more than it is by dealerships. The 3.73 has its place for those towing less than 10K or so and more interested in mpg. I know most towing over 10K will probably opt for the Cummins, but the 4.10 in the 6.4 Hemi may be a good choice for many depending on how often they tow, where they tow, and how/where they use the truck when not towing.
