We have had a similar leak in our 381, in order for water to get there it has to get between the exterior cladding & substrate. The first attempt by the dealer was unsuccessful, I went over every seam & joint, I concluded it was leaking through the side slide out window. I sealed the exterior of the window frame with silicone & it hasn't leaked since, I plan to remove the window & reseal it properly, hope this helps you.
