On a 2018 RT 27 OB seeing signs of water leakage on the inside woodwork and lower aft corner of window. Not sure how to really fix this. Am thinking I need to remove the inside trim ring to access the window frame to side wall interface and seal with caulk. Not sure if this is the way to go. The top of the trim ring is partly covered by the wooden "shelf" above the window. Does this need to be removed in order to remove trim ring or can I just slide trim our from under this wooden piece? Any idea on who the manufacturer of these window are? Would be very nice to see installation instructions for windows before doing anything. Any feedback from those with experience with this problem would be appreciated.
