rear window leak
Help needed. I have a 25ft. 2005 fb safari. I have just discovered a leak which I believe is coming from the area of the rear window. I found a small puddle of water under the dinette and upon further exploration, pulling the linoleum up from the rear wall, found extensive rotten wood. It is obvious the leak has been around for a long time. There is no water running down the windows inside and the drains are not clogged. I have recaulked skylight, running lights, fantastic fan and window. The first trace of water that I can find is coming in at the bottom of the window frame in the middle. Any suggestions would be greatly appreciated.

Curved window or flat.
Here what I did if it’s the curved.

Thank you for replying. I don’t have curved windows. Wish I did. Just 1 rectangular one. Back to the drawing board. Thanks again.

I am hunting a leak around a rear window as well. There are a lot of rivets back there, any one or 2 leaking would let water in and puddle with a good rain/melting snow. Also clearance lights above the window and some AIRSTREAM letters are mounted with posts that penetrate the skin
In your case, I would do close inspection of all the rivet heads to see if there is any gap where they should fit flush to the skin/frame. Any gap is likely to leak. Can use sealant like Captain Tulleys crack sealant. If there is any seam sealant peeling back including above the drip rail above the window, it will also leak. Make sure all the sealant at these seams are intact. At 14 years old, good chance some of not all have some drying and pulling off the surface.
In my opinion this is regular maintenance with AS, there is a kit if sealants sold by AS which includes all products for resealing seams and around windows/doors
Good Luck!

Many leaks are caused by a seal at the back end of the trailer. Not sure if yours has a bumper storage compartment or not but the plate for that goes under the trailer and funnels water into the floor area.

A poor boy way to find leaks is to pump positive air pressure into your trailer using your shop vac. Go to Lowes or Home Depot or Amazon and get some gas leak detector solution after you check the size of your bathroom or shower fan and also get some flexible aluminum home vent duct the best fits into the fan housing and also duct tape and painters tape. Put some duct tape around one end so it fits tight in the fan housing Use some cardboard and tape for larger gaps. Attach your shop vac suction to the other end and seal it.
Run the vacuum, shut the door and go around the trailer listening for large leaks in the windows, compartment seals roof vents, A/C unit etc. Seal them temporarily with painters tape or fix them as you go. Now that you have the big leaks fixed, get your gas leak detector solution and spray it around your back window to find the offending leak.

Don't overlook a thorough inspection of your tail lights. Quite often the gasket for the lens is installed on the back side of the can. The gaskets go between the lens and the can. The water is kept out of the interior of the Airstream by a plastic interior cover over the hole where the lights install. It is attached and sealed to the backside of the outer skin. That plastic can crack over time allowing tail light water into the Airstream. If it is cracked it can be cleaned and sealed with caulking. Put everything back together with the tail light gaskets between the can and the lens. Of course replace rusty cans and dry rotted gaskets as needed.

I had a similar problem
Water was getting in on a heavy rain, collecting in the aluminum tray between the inner and outer skins. I discovered the seal on the outside between the glass and the window frame had gone bad. I fixed it with some silicone.

Did the same, 2008 International, panorama windows in the rear. I had to caulk the glass/frame and window frame to the body.

Hi, it is well known that water can leak inside by the rear bumper cover area. Later in about 2012, Airstream added a rubber seal between the bumper cover and the body. You can remove the chrome trim and seal the seam between the bumper cover and the body. I was able to seal the area between the chrome molding and the bumper cover on my Safari. Mine has never leaked, but I sealed it anyway.

Some of my leaks could only be found by removing the inner skins and sit out there on a paint bucket in a rain storm to find out where they were coming from.

For what it's worth, Silicone seals should be avoided on most RV's as most of the joints are not rigid so there is a lot of movement and Silicone sealants tend to crack in a couple years. It is messier while uncured, but use the polyurethane sealants that Airstream recommends. I like the Silkaflex 221.
