Well, I've been with my dealership since 96, (still same owner), and I've purchased 3 Ram Dually's from them since June of 2010...before that, I'm clueless about the Dodge truck, but I can state that the 68RFE tranny is a very good transmission, (had in my first two), and truck in my sig has almost 22,000 miles on it...zero issues, GVWR of 14,000#, RAWR of 9750#, 385HP with Aisin tranny gives it 850ftlb of TQ...with the 4:10, has a GCWR of a little over 37,000#, brand new frame, new front and rear suspension and a medium duty engine (cummins), strapped to a medium duty tranny (Aisin)...LOVE IT!!! Tows my piddly 16,200# 5er all through the mountains effortlessly...One of the best looking trucks on the market today, inside and out, but all that is just my humble:), opinion...The truck is a towing animal...wrapped in the lap of luxury :)
I would highly recommend one based on my experiences with a 2010, 2012 and the 13' in my sig.....
