Everyone else is tending toward the fuel side of things and white smoke generally does indicate a problem with unburned fuel. The one thing nobody else mentioned, and I may be off base if it isn't turbo charged, is that a siezed turbo will cause the same problems. If the bearings were gone out then it would typically smoke black and use oil, but not all turbo problems are that drastic. Knowing that the truck is being driven by a younger, school age, girl I know most are always in a hurry. So taking the time to let the engine idle down before shutting it off is probably the last thing on her mind. That being said the turbo would definately be a place to start looking if it is in fact a turboed engine. Too, if the turbo has a wastegated, the same problem can occur if the waste gate is stuck open. In either case, siezed or open waste gate the injection pump is supplying a normal amount of fuel throughout the RPM range but there simply isn't enough air present to burn all of it, hense the white smoke. Good luck.
