Ram 1500 EcoDiesel Max towing number released

THe lack of any real payload is why a 1/2 ton diesel just doesn't make sense to me. The current top of the line gas offerings can all easily handle whatever you can "safely" tow with these trucks. You buy a diesel because you need/want the pulling power but when the severly lacking 1/2 ton chassis becomes the weak link I can see why not everybody is jumping onboard with offering 1/2 ton diesels. Maybe Dodge knows something we dont, but I doubt it. Still trying to understand the logic behind a 1/2 ton diesel...
