Leaking behind the gutters

I am looking for help. For the past year when it rains it appears that water is dripping behind the gutters on my trailer. I know it’s hard to tell this for sure but when the AC is running for example, you can see water dripping behind the gutter and not over it. Is this normal, it is driving me nuts and each time I bring it up to the dealer they till me it’s fine.

Do you have a picture by any chance? I bet it goes over the gutter and seems like to goes behind.

I have the same issue and same response from dealer. I have found that the track above the gutter also has a seam (not sealed) and when the water runs off of the roof it is getting behind the track and then the gutter. Also the awning stitch at the top needs to be treated with a water sealant.
