If you are leaning towards the RAM, then understand that the 68RFE version is tuned to 370/800 vs the Aisin being tuned to 385/850. The Aisin seems to have a firmer shift pattern versus the 68RFE which gives a feeling of flaring between gears (fixed with a different calibration like I did for my truck). Also note that the Aisin dually also upgrades from a 11.5" rear end to an 11.8" rear end and a finned differential cover. If I were buying a dually for pure towing duties, I would strongly consider moving towards an Aisin.
