Diesel rule #1: Don't run out of fuel.
Diesel rule #2: If you do run out of fuel, it's going to suck to get started again.
I would soak a rag with gasoline and have a buddy place it near the air intake and let it "sniff" it while you crank. Don't hold it too long while cranking, because you don't want to over-rev your engine. It will run a little rough on gasoline vapors, but it will help get a cold, un-primed, un-charged, air-filled-fuel-system truck running again.
This is way more relevant for the older trucks with mechanical (either diaphragm or camshaft driven) fuel pumps. Those things only produce pressure when being turned, so having the engine running (poorly) on gasoline vapors gets it going much faster.
It should still help you purge that air in the system in a newer truck too.
