Question for owners of late model Ram 2500 6.7 Cummins Diesel Owners

I don't expect to get a lot of response from this question because it is rather specific, but can't think of another way to get the data.



If you are towing with the above specifically mentioned vehicle, say 2011 and newer, what gear ratio do you have in your truck, what are you towing, and what is your typical towing fuel mileage?



I am asking this question because I'm considering changing the gears in my truck from 3.42 to 3.73, because by the specs that I have found, I'm over the limit as currently loaded.



I've tried the Cummins forum, but the majority of those guys are young hot rodders, and don't really give a flip about towing or fuel mileage.



Thanks for any input you may have.
