Yes, I do the same thing. Keep it around 50-60 mph (conditions allowing ) and towing with both the 2500 and the 3500 the results I stated are the same. I'm very easy on my trucks, and having worked on diesels and also a Cummins tech for well over 37 years I think when I tell the truth about my experience towing with the new Ram, at least somebody might listen to reason. I could care less what all the pros behind the keyboards claim on TDR. I don't listen to most of the garbage I hear on those forums, or the internet. I don't really care what you think, and for you to tell a person that it's OK to overload his vehicle is one reason I don't listen to most of the dribble coming off someone's keyboard. Now go to TDR and ask those fine folks to tell the real truth about the way there trucks REALLY OPERATE. I pull this 17,500 lb trailer all over this country in all weather and conditions fulltime. I know what these trucks are capable of, and I hope the OP will listen to experience pertaining to the 14 and 15 Rams.
