RAM all day everyday. Im on my second 2500 Cummins, first was a 2010, current is a 2015 and Dad's is a 2016. Have a 2011 F-250 for a chase truck at work because .gov and I didn't get to choose. It drives smoother and is faster but it doesn't tow nearly as well, doesn't have an engine brake, sits lower and has been a maintenance beast. 2 DEF systems in 8 years, a turbo and a bunch of other stuff. If you work on them yourself you will appreciate being able to reach into the engine compartment on the Cummins, thats not really a thing on a Powerstroke everything is crammed in there so tight and the air filter cover is a MF'r to get on/off. IMO Ram has solved the DEF/emissions bs better than anyone which is significant because the tuner/delete industry has been under attack significantly which can be a whole other thread/rant. They both build good looking trucks but I'll take the Cummins reliability everytime and have put my money where my mouth is twice now.
Im no mechanic, just a wildland fire engine captain that drives these trucks daily all over the west with lots off offroad and towing in generally rough/shitty conditions. Take it for whatever you think its worth, there's diehard fans on both sides for reasons. Ive never heard of anyone swapping a power stroke into Dodge but Cummins swaps into Fords are not uncommon for custom builds.
