Seems there is a big disconnect between what the "Build link" allows you to build and the specs with towing links and the specs out at RAMBODYBUILDEER.COM
Called RAM customer service and they confirmed the discrepancies but had no idea which ones were correct. In my case, I want the 3.92 rear axle ratio on a Tradesman 4x2 that I cannot build using the build link but is shown as available everywhere else.
Asked if I could be pushed up the ladder to someone who could address it and was told they do not have those phone numbers. I got on my own the phone numbers for media relations and talked with a very nice person who said she would share the information quickly to see whether the specs are all wrong or the build site is wrong. Told her if the build site was incorrect that they were losing customers.
