Rain leak in bedroom, wet carpeting

[ragnar33]

Hello, we have a rain leak in the left rear corner of our 2014 Jay Flight 36 BHDS.
The carpeting in the corner between the back wall and the slideout gets wet after heavy rains with strong winds hitting the back of the trailer.
I have checked very thoroughly for places where the water could get in, including the corner caulking, and even caulked around the top and sides of the rear window. I have also checked the roof and the seals around the slideout and found nothing. I will caulk along the bottom of the rear window for good measure, it seems to be the only possible source of the leak.
Any ideas?

I don't have much experience with trailer leaks but I'm curious if your slideout has an awning over it? I was heavily advised to add the extra awning over the slideout from an independent RV service man. It cost me an extra $500 dollars from the dealership before I took delivery but I feel it's worth it in the long run.
It will help keep leaves, debris, and rain out of the top of the slideout, esp. over time
Hope you find your root cause
good Luck

Thank you kayakterp, yes I forgot to mention it but we do have awnings over the slideouts.

Do you have a rear ladder? Maybe check those areas.

The lights have been known to leak. Did you check the roof too?

Thank you troutslayer and RedHorse1,
Yes, I have caulked ladder attach points and I have checked roof very carefully.
I have also checked corner caulks, so I am hoping that caulking the bottom of the window will fix it. I won't be able to check it until the carpeting dries.
