I have a 2004 motor home with a caterpillar C7 engine. The owner's manual has much to say about starting, warm up, idling, cool down, etc. After a cold start you do have to wait a few minutes for the air pressure to build for the suspension and to both release the parking brake and be able to use the service brakes. At that time it is recommended that you drive gently as it will warm up faster under a load. For shutdown it is recommended that the engine be allowed to idle for 3 minutes to allow engine temperatures to stabilize and for the turbo to cool down while oil is still being circulated. The book goes into some detail on how idling the engine is actually detrimental with the major issue of carbon building up around the rings. From experience this build up can make the rings stick which is what really causes most engine to require a "ring job" and stuck rings can damage the cylinder walls. Keep in mind that this 7.2L engine weighs about 1,200 pounds so there is a lot of cast iron to absorb heat and also to stay warm afterwards.
From a cold start in below freezing weather this engine will never warm up idling. On the road it can take up to 13 miles of driving to get it up to temperature. Weird is that while it is a Diesel pusher the cooling fan has not control. It is direct belt drive off the engine so needed or not that HP robber is always there.
Diesel fuel doesn't vaporize and burn at low temperatures like gasoline. This does cause some issues when cold including smoke, low power, and worse oil dilution. However there is no reason to run them forever except in extremely cold temperatures and with the price of fuel I can think of better things to do then burn off a gallon/hour. Many rigs now have auxiliary power units of some type for non-engine driven heat and AC and many truck stops have ducted heat and air for overnighters.

Just yesterday I was on my daily walk and passed by a giant diesel pickup parked by the curb with a big "camping" trailer (portable house) behind it. The engine was running. An hour later I passed it again. Still there, still running.
I know that diesel engines in the old days were hard to start, took a good long while to heat up, and ran inefficiently until fully hot. But that isn't true now, is it? Aren't automotive diesel engines supposed to fire right up and be driven away immediately, like gasoline engines?
