It would have to be some scenario involving a full-throttle climb up a pass, say to Sunrise or Paradise at Mt. Rainier. Or towing a trailer up there at a more moderate pace.
These engines are overkill and don't even warm up all the way unless you're climbing a hill. Search around for TDIwyse's thread where he was talking about cold-weather warmups and posted a coolant temperature graph for his commute - a couple years ago now. He's also posted a recent graph of exhaust temps that show rises when he's doing ET kinds of things, and mentions not seeing them rise otherwise.
