smoke on startup

[dashhho]

Well I don't think this is a big issue but figured I would hear some opinions in the case it is. My truck sat for around 3 weeks. When I started it up there was some whiteish smoke that came from what I believe to be the exhaust, but not certain. I was sitting in the drivers seat and seen it come up on the drivers side so I assume it blew forward from the exhaust.

I have started it everyday since (for about 5 days). No smoke.

Any thoughts?

Could have just been moisture in the exhaust.

Or better yet, an occupied mouse nest in the exhaust.

Probably just condensation. I wouldnt worry unless it starts doing it after its warmed up or if you start losing coolant
