I know you've been here a while, but WELCOME to the forum, Jeff.

Almost invariably, that type of smoke is caused by worn valve seals. My own experience showed cold-start smoking was stopped by replacing the valve seals...and my truck had some 220,000 miles on it at the time. There are many testimonies on this forum that support a valve seal replacement took care of the smoking. I did note, on my own repair, that it took a couple of days for the smoking to stop completely.

What happens is when the engine is hot, then shut off, during cool-down oil is permitted to leak down into the combustion chamber. On start-up, it takes a while for that pooled oil to burn off. If the seals are really bad, then your truck would smoke even while warm.

Please post how many miles the truck has on the clock...that helps with diagnosis.

That's my suggestion, but it's always good to wait 'til a couple other members give their advice.
