I have a leak at the rear bed room slide, it is leaking at the right bottom corner if you are standing at the foot of the bed. I went out a few minutes ago to see if I could tell where it is coming in...
If the coach is tilted a little off of level, and water does get on top of the slide, it may run under the seal and migrate to the bottom of the slide. Check to see if a slight tilt in the opposite direction corrects the problem.
