Agreed. Do you know if they replaced the oil cooler as well? The coolant passages in the oil cooler get clogged (which is why a lot of us run coolant filters) and starve the EGR cooler downstream. The EGR cooler overheats and fails when the exhaust hits it, leaking coolant into your intake and cylinders. The white smoke could be burning coolant.
That may have been your truck's problem to begin with.
