Pulled this from the 6.7L Diesel Supplement for anyone that might not be aware of the additional idle time before shutdown necessary when towing.

SWITCHING OFF THE ENGINE
Turn the ignition to the off position.
To prolong engine life (especially after
extended high speed, high ambient
temperature, or high GVW/GCW operation,
such as heavy loads or heavy trailers), it is
recommended that a hot engine be idled
for 3-5 minutes. This allows the
turbocharged engine to cool down. For
more information on GVW/GCW, see the
Load Carrying chapter in your Owner’s
Manual.

Looking thru the 6.7 tech manual, I see the turbo's are water cooled. I know that alleviates a lot of the issues of a "hot shutdown" as they design the coolant chambers so that water will continue flowing when the engine is shutoff via a "thermo-syphon". As the water heats up, it rises and will draw cooler water from the engine.

Still a good idea to let it cool, but I think its less of an issue than with the old style turbos that were only oil cooled.

Interesting Garrett White Paper on water-cooled turbos:

Ford specifically tests their engines for survivability of shutting down after an extreme run. Turbo cooling through coolant convection is much improved over the early days. As for oil, Ford diesel oil isn't even a blend unless you specifically request it. It's just standard 10w30 diesel oil.
I was told at the dealer that there is a diesel blend and not full synthetic that is what they normally put in diesel trucks. it's about $6 a quart. Maybe $7. I don't use that, I use full synthetic thats why my oil changes are around $200
As for the glow plug it's a habit.
