Mysterious Water Leak

Hello All,
I've been a lurker here for many years, but have never posted. Haven't met most of you but we did spend some time in Quartzite this winter and met up with a few outstanding Foretravelers. Everybody except for that Twig guy.  :>)

Unfortunately, I discovered a water leak in our unit this morning and I can't quite figure it out. We are in the Dallas, TX area in a campground and there were bad thunderstorms last night with heavy wind and rain. This morning I noticed the carpet was wet between the couch and the kitchen. Underneath the sink is bone dry, so pretty sure it's not from a leaky pipe. I was up on the roof and there are no roof penetrations in that area

Could rain leak down the wall from the roof seam and onto the floors? Everything looks pretty well caulked up around the roof seam and trim piece. Could it possibly coming in the kitchen window then leaking down the walls onto the floors? I'm at a loss and have done some forum searching but am not finding any answers.

Thanks!

One possibility of many.  The windows have rounded corners and the openings they are mounted in have square corners.  Their is not much room for error in the gasket installation.

The window gasket stinks over time.  Use a very thin feeler gauge and make sure the gaskets have not pulled back from the edge of the windows at the corners.  The gaskets should be flush with the edge of the window frame.  Only takes a few minutes. 

I recommend everyone check their coaches.

Do you have a living room slide?

If so  inspect the fiberglass on the outside, around the slideout opening.  If any gaps at bottom and/or 1/4 of the way up the sides, seal it up, to the edge of the slideout gasket..

Also in those years, common for the slide to "bow" in the middle at the top, which can cause a small leak sometimes intermittent.
A twig or anything on the top surface of the slide that co  it is interfere with the slide seal can also be a source.

Not sure why my profile is not posting at the bottom of my posts. I have the info in there. We have a 2000 U295, no slides.

Hey Twig! If it came through an A/C seal, wouldn't there be water running down the walls on the inside of the coach that would be evident? I'm just asking, I don't know. I checked underneath the drawers in the kitchen that are closest to the couch and yes the floor is damp under there too.

What a pain!

I also have another leak in the very front of the coach between the cabinet that used to house the TV and the one beside it. There is no gap there, but water is seeping down and landing on the dash, steering wheel and floor. The space above where the water is coming out is hollow, where the TV and A/V equipment used to be. I have felt all over in there and cannot find any dampness, so it is not coming straight down. Frustrating!

If your refrigerator is on the same side as your leak check inside the side vent panel, if the wind blew the rain in it could find it's way down into the coach.  On my coach there was a low area directly inside the opening that I filled with Dicor self leveling to direct any water that may get in back out.

Bill,
Fridge is on opposite side of the coach.

Thanks

Possible places coming from

AC unit gasket. You would be surprised how far the water travels from there.
Refrig vent  Roof and or side one
Windows themselves or window seals
Seam between roof and side wall  It can look like it is sealed good but may not. Also could be coming in from screw holes holding trim on. 
Wall trim on side.
trim around pipe vent.

For the front like Michelle said, clearance lights. Also check sealant on the front cap, air horn mounting screws, any antenna mounts..
