I'd strongly urge you to contact your dealer tomorrow morning. Don't wait until later, this is something that you really need to report ASAP !!! The longer you wait, the longer any water will have to damage the walls/insulation and the more difficult it will be to properly repair the trailer.

It is under warranty, but the factory may (maybe not, who knows) feel that it is your responsibility to inspect and seal the roof seams on a regular basis. The owner's manual is specific on this and it is an exclusion to the warranty, so reporting it as early in your ownership as possible will benefit you if there is any question about responsibility.

Tomorrow morning, first thing, call the dealership. If he is not able to get you in for service immediately, then it would benefit you to cover the trailer with a blue tarp to protect it from further damage. Take pictures of the tarp covering the trailer, you may need to prove that you did take action to prevent added damage.....

Good luck and keep us posted.
