Volkemon did an extensive write-up on water entering under the front running/marker lights and working its way down behind the transition panels. Check for telltale stains or dampness inside the ps overhead cabinets.
LOL.. no I didnt!
But thatns for the credit. I did the TV mount up there, and it was water free.
* I know what it was. I posted 'Peace be the Journey' 's pictures of marker light water damage.

The shop I got it from
thought that was the leak... and even replaced one of the markers with a mismatch...and still didnt fix the water leak(s) from around the windshield.
On mine the floor/door leak was tricky. The seam between the walls and lower side panels were not sealed, and the water went in behind the trim piece. Then it leaked all over the pass side floor, and filled the stairwell. I happened to notice it when I was watching the 'drool' lines of white from the gel coat flow down the side...and noticed the pattern coming out from under the trim was MUCH different than what was going in...and WHY was it going in?!??!?
Pulled off the trim to find the seam between the wall and floor was never sealed, and funneling water in. OW!! Put a big bead of 'urethane in the seam, put the trim back on, no more leaks since then.
Found it. Pics you want are page 2. WOW. I forgot all that...um....FUN.
Been leak free ever since, and the coach smells great after being parked now.
EDIT - forgot link....
