I do not want to ruin the fuel mileage, but also do not want it to struggle too much when towing, despite its being a light trailer for a diesel really.
I have read many other reports and opinions with rergards to rear axle gear ratios. The consensus with regards to your wants is that the 3.73 gears are the best mid range that will provide descent pull and MPG. After learning more about the ratios and performance, I was a bit worried that my new truck may not have had the best gears for my needs. According to Dodge's website specs all 2011 Ram 3500's come standard with 3.42 gears and my needs fit more towards needing 3.73 gears. So I found my dealer sticker price sheet and was so happy to see the 3.73 gears were option added to my truck and to be sure, I confirmed this with the dealer.
