Rain gutter installation

[homer1959]

I've noticed on my new Jayflight 2 spots where the water from the roof top find his way to drip on the side of the trailer .

Couldnt see any hole or spot where the putty or butyl is missing behind the roof top side trim.

My question is how they install the gutter on the side of the trailer. Is it kind of sqeezed behind the trim and held by the same screw holding the trim ?

Or is it made in one piece , integrating side trim and gutter in 1 piece

I looked and looked and couldnt figured out how the water can leak on the side of the trailer, and at one place behing the awning

On mine the bottom of the rain gutter was caulked, and it was missing in a few spots.
