Which axle ratio for 2013 Ram 3500 dually?
I think I narrowed down to getting the following combo: - 2013 Ram 3500 Megacab Dually Diesel with short bed - 2014 DRV 36ft 3-slide model I've been looking at the Ram configurator and realized...

I have a 2012 with 3.73s and 35" tires. This is pretty close to the 3.42 ratio. I hate it. I have a hard time getting heavy loads moving, the truck has to turn a lot of RPMs to get the load moving. Also, the torque converter does not lock up on some of the steep mountain roads we haul our horse trailer (10K) up. These roads take 20 minutes of non stop climbing doing between 15 and 35 mph. The transmission just keeps building heat. On the highway, it does great. Everywhere else, it leaves me wishing I would have chosen the 4.10s so I would have been closer to a 3.73 final ratio.
I'm looking at getting a 2014 DRW Ram with the Aisin and Air Suspension. I will be getting 3.73s or 4.10s, I would never consider the 3.42.
Your 68rfe has a first gear ratio of 3.23:1
The Aisin has a first gear ratio of 3.74:1
In addition to the large difference in first gear ratios, I wouldn't be real surprised to hear the torque converter used behind the 800 lb ft Cummins with the 68rfe transmission was never really designed to handle all that torque.
So are hearing about 68rfe torque convertor failures?
