All three, Ford, GM and Dodge have all had their good and bad products. I wouldn't consider towing unless I were towing with a diesel regardless of brand. Mid 2000 Dodges were notorious for transmission problems, pre 2005 GMs had injector issues and Ford has gotten a really bad rap over its infamous 6.0 Power Stroke and many of the newest models offered by the three suffer from emissions equipment quirks and problems. Do your homework, there is a ton of review information on line about good and bad years for all three and how to fix them so you will have a dependable TV.
