2011 Duramax vs 2016 Cummins
I currently have a 2011 GMC 2500HD 4x4, Crew cab with the Duramax Diesel engine and Allison transmission. The truck has 155k miles on it and I am looking at the 2016 Ram 2500's with the Cummins diesel...

What transmission? 2500 Cummins are available with both a 6 speed manual and a 6 speed automatic. The 68RFE automatic is a very reliable transmission that will return years of service. Depending on rear end ratio it could be a real good unit. The 3.42 standard rear end ratio works good for most people. But I would much prefer the 3.72 or the 4.10 for towing heavy.
Maybe so but the 3.42 is the ONLY option for any RAM SRW truck. 4.10 and 3.73 are available along with 3,42 on their dually trucks.
Op you should consider a 3500/AISIN with rear air ride. 68RFE is a good trans but the combo I mentioned will allow for towing much more if you decide to in the future.
