My Safari had a leak at the that would wet the floor at the rear bumper area. If your trailer has not been repaired, it is leaking also.

In addition to your suspected Fantastic fan, the leak at the closet shelf could be from the plumbing vent cover that is above the closet. If there is a skylight in that vicinity, it would be a good bet that it is leaking also.
Good luck!
