Back Window Leak

I have a 2021 171 I bought it used and have multiple small problems with it. The major one right now is a leak that puddles up in the track of the back window above bed. Towed it in a windy rainy storm and also had some leak in back left window (moisture on mattress) also believe there was some water on floor under bed. SO I wanted to hear from people that have had a similar problem and where that possibly found the leak. I believe its probably not the window but coming from the top somehow ..

Thanks for your input and ideas i need to get it fixed asap
