best Ram Cummins Forum?

In the very early 90's, I subscribed to the TDR magazine, probably within an issue or two since it's beginning. I still have some of those early issues... somewhere. Precursors to the commercialization of the world wide web, I looked forward to receiving every issue, as a window to see how other folks made use of the increased hauling capacities brought about by the relatively new introduction of factory equipped turbocharged diesels in consumer pick up trucks.

Fast forward 27 years to today, with the web in every pocket, and I'm not sure if a civilized Cummins diesel forum exists. The choices seem to be between forums that are as quiet as a funeral parlor, or as cantankerous as a sports bar, with no middle ground inbetween.
