I have 3.73's in my DRW C&C only tow about 1/4 time.. I think they are a good all around ratio..
And I am grossing over 24K with 3.42's and they work great. Bobtail at 80 is only 1750 RPM with good mileage to boot. The Aisin transmission is the ringer in this combination, as it gets heavy loads rolling with it lower gears. Again towing in 5th at 60 MPH is 1750 RPM and at or near max torque. Drop the trailer and you have a second overdrive to cruise the freeways at a conformable RPM. What is to not like about that? If I decide to go to a duallie and had the same 16K trailer with no plan for a heavier trailer I would look for 3.42 geared one.
With 6 gears even with 3.42 final ratio there is a gear for every situation, if you have the Aisin. I would not do this with the 68RFE. Only place it wins in reverse is much lower than the Aisin.
Now do I need a duallie with a 39'4" 16K 5th wheel. We just returned from Az 1450 miles and had a lot of wind, and to combination handed just fine. Same going down in the fall. I see no need for a duallie and DW does NOT want one period anyway, as that is our only vehicle in Az. The 2013 3500's forward(think new frame and front end) are so capable that until one has used one it is hard to understand. They are heavy beasts and can handle a lot.
