Small crack in fiberglass - how serious?

I just purchased a new HTT, and discovered a small crack in the fiberglass shell. Unfortunately, I didn't discover the crack during the final walk-through, I found it after I brought the camper home. Here is a photo:



If you run your finger over the crack, it is dimpled outward very slightly, and I can't determine an obvious cause. I left a message with my contact at the dealer and I'm waiting for a call back. I have another minor warranty issue that they are taking care of, and I'm hoping they will fix this at that time.

Can anyone offer me some advice on how serious this issue might be, and what the proper repair is? I want to make sure it doesn't spread or lead to water damage. Thanks very much!
