Something leaking upward!

[dshogman]

Right side of coach (PS) in line with the leading edge of the rear slide, and 35" from the right sidewall. Two days in a row, a 3-4" spot on the carpet. No real odor. (No, not the dog.) Nothing visible leaking from the ceiling. From the outside, it looks to be behind the right rear tire well.
Any and all thoughs appreciated.
Thanks.

Look to see if the gasket is folded back at top L corner of the slide. Will get carpet wet in front of r night stand

Just a thought:

Are you driving the Coach in the rain?
I ask because often there is a low pressure area inside the Coach that will actually suck water into it.

I avoid this by running the dash blower at all times the Coach is moving, which causes a slight positive pressure in it.

Not that it's happened now; just with 2 of my other Class A units.
