I had that happen on my 2013 Laramie with sunroof. There are water drain tubes that run right along side that pillar and down to the outside of the truck. Supposedly it's not just one solid tube running to the outside to drain the water from the sunroof. Mine came loose twice (fixed under warranty). They had to reconnect the drain tubes near that pillar. But since your truck does not have a sunroof, I'm not really sure if drain tubes would be in that area.
