While I lack your particular truck, I've had three diesels since 2001, and all of them warm up very poorly while idling.

All three owners manuals say start them and drive off to warm up. Needless to say, easy on the throttle until they do warm up. In any case for any engine, the first 15-30 seconds after a cold start will see oil still trying to reach distant points in the engine. After a cold start, a few seconds checking seat belts, mirrors, etc should be plenty.
