They are both very good, very strong trucks. FishOnOne will always have a negative Ram story to bring up, so I will bring up a positive one. A former coworker has a 2010 Ram 5500 that he uses in his tow truck business. It is the Tradesman trim with vinyl floors. It sees severe service every day, and he loves it. In fact, his wife works as a service writer at a Ford dealer, and she recommended the Ram because she was seeing too many significant Powerstroke diesel issues every day in her job. Believe it or not, but that is a true story.
FishOnOne though has a bit a valid point about the Aisin AS68RC equipped 5500's. That transmission was not quite oup to medium-duty specs as it wasn't really stronger than the 68RFE at the time (in fact, some mention it as a little weaker for some reason, but it had PTO that the 68RFE does not have). However, the AS69RC is a very beefy unit and that is what is used on the 2013 and up chassis cabs. That transmission has guts that are just big and robust like a true medium duty transmission needs.
