The RAM may have the same transfer case as the QTII. As these cases get more mileage on them, I'm hearing more and more reports of clutches overheating, especially in severe conditions, and 4WD gets disabled. I think there was a flash for this awhile ago as the service 4WD light will come on while driving in the sand. There have been a few reports of clutches wearing out or burning up.
So the marketing thing about full lock may not be entirely accurate as the clutches will slip... and those clutches aren't as robust as the engineers thought.
