Excessive steam from exhaust

[greatmizzou]

Has anyone noticed an excessive amount of steam from their exhaust on the 6.6 gas?

 

It was sort of humid out and The visible steam from the exhaust when I drove a short ways was concerning.  Im wondering if there isnt some fuel mix issue with these trucks, which reminded me of a short lived cold start problem I had last winter.  The dealership sort of shrugged and said everything looked OK, but I wonder if we will get a slew of rough start complaints again this winter

Water is one of the things produced by combustion.

 

If it was only driven a short distance it may not have got the exhaust system hot enough that the exhaust stream would include steam (invisible) instead of water vapour (visible -- but often incorrectly called 'steam').
