Its a truck, just use it whenever you need it to do whatever you are doing. We have trucks for our construction company. If the truck needs to start, you start it. If it needs to drive five miles or five hundred, thats what it does. Why would a diesel truck be any different from any other truck. Warm it up a bit to get the oil pressure up, same as any vehicle. We dont treat our diesel trucks any different than our gas ones. One main thing all my mechanic friends have told me is, if you have a turbo, do just shut them off hot. Let them idle out for a few minutes before shutting down. This gives the turbo a bit to cool off. Other than that, I dont think the millions of work trucks out there are getting and special treatment as far as not driving them on short trips.
