White Smoke?

[fordtruckthing]

Had a few hour drive this past weekend and truck ran fine. My truck has white smoke on start up in the cold winters, which I'm fine with, but never in the warm months. It wasn't cold at all this past weekend and the morning I started the truck after the long drive the night before I got a lot of white smoke then it went away after it warmed up and didn't notice anymore the rest of the day. Did the same thing the morning I started it after getting back.

Anything I should be worried about?

Thanks,
