Your information is dated concerning the current offerings of trucks. Whether you get the Ram with Cummins/Aisin, Ford with Powerstroke/6R140 or GM with Duramax/Allison, you will get a quiet refined power train. Subjectivity, price and availability will have you choose one over the other, but all three can get the job done without regrets.
If you are looking at used models, each has had a history they have hoped customers have forgotten. You have the hindsight to search out the most desirable years and configurations based on others experience.
