Coolant leak, most likely the intake manifold gasket, but it could be something dumb like a leaking coolant temp vacuum switch.

A couple of things come to mind. Drive your truck till it's fully warmed up. With a person following you @ 30-40 mph. remove your foot off the accelerator. If the person following you happens to see white smoke, your valve guides are probably warn out of tolerance. Chevy's do not have or ever have had valve stem seals from GM. The stamped umbrella cup on top of the valve springs are supposed to keep the majority of the oil that drips off the rocker arms off the valve guide holes.
If your buddy following you sees no smoke, have your cooling system pressure checked at any car dealership or independent mechanic to be sure there are no internal head gasket problems.
Remember, pick-ups have a very long exhaust system. I'm sure you've heard yours snap and crackle as it starts cooling after a long hard drive. As they cool off cold moist air enters the long system. When you start it up you're bound to see white moisture from the exhaust for a minimum of 15 minutes especially in the winter.

White smoke is moisture, blue smoke would be unburnt fuel, and black/brown smoke would be burning oil.
If it's white it could be moisture in your fuel, but it would be blowing out white all the time, or until you got rid of the water in your fuel.
Since it's only when you first start it up, it's probably more of a condensation problem. When you shut off you engine when it's hot, as it cools moisture is condensing in your carb., cylinders or exhaust.
How to fix it..???? I'm not sure.

if its white smoke or steam...its coolant getting in your combustion chamber and burning off ...possibly a head gasket with a leak at a coolant port close to a cylinder...if its blue smoke its oil and could be weak rings or valve guides going bad. guides are cheaper to fix.

that is coolant burning that could be a blown head gasket or a cracked block or cracked head

valve stem seals are probably going bad
