For sure check the vent slots like Dan pointed out. However it sounds like the putty tape seal may be gone. A picture of your window sill may help confirm this.
I cannot remember the year of your camper but thought it was a 2003 or newer. Which means the windows are like mine. It is hard to believe, not impossible, that it is coming in from the actual crank out window as the sill is really high lipped and you would see the water out in the open.
What leads me to the putty tape seal being gone is you said the water was coming in "under" the sill and down the wall. The putty tape can release from the siding and not stick. I have seen this myself. This then leaves a small air path right to the inside of the camper. OR they set the window not in the middle of the hole and just missed the seal in some places.
See here. The dirt marks on the siding showed me that the putty tape lifted from the camper siding over time.
I also had one window where when I took the inside flange off to insulate the air space I could see day light shinning in the window flange on the side of the camper in the corner where the putty tape was not sealing. The corners do not fit as well as the top/bottom and left to right sides. The corners are not an exact match, the radii are different so more is exposed.
Any chance of some pics of the area the window sill?
If it is the putty tape not sealing, this is not a hard thing to fix. Like Dan said use butyl rubber sealing tape. This post may help. It is an entry door but a window seals up the same.
Hope this helps
