Hi Mike,
If the truck's cold it might steam anyway at first. If it's coolant,
you should be able to smell anti-freeze in the steam coming from the
tail pipe; at least I could the only time I've ever seen a leak like
that.
Spark, fuel, compression are all good? Believe me, I'm sympathizing: I
can fix most things on cars and trucks, but diagnosing problems is
really hard for me.

The real problem is revealed by the large cloud of white smoke

vehicles
