I have a similar issue with my Outlaw 29H and waiting for a date to take it into the Thor Service Center. I think my layout is similar to yours.
Once in a while after the coach has been sitting and I start to move it, I will get water dripping behind my head at the drivers seat.
My dealer said it was the window seal (lack of one from manufacturing) around the window of the slide out. I couldn't see how the water would get from there to just behind my head but that what they said.
A couple weeks after I got it back home from the dealer and the coach was sitting in the driveway, we left for a trip. I was no sooner out of the driveway and it started dripping from the same place..... just behind my head at the driver seat.
I have been up on the roof too and can't see anything but the water has to be getting in somewhere..... and I don't think it is the slide.
The funny thing is it can rain like crazy and there is no water in the coach anywhere.... it is dry everywhere I check. And it does not always leak either. We have had a ton of rain here the past 2 months and it has not dripped water again now in 8 weeks.
