When at the factory I asked if it needed caulking and the answer was is it leaking or is it lose? If so yes. But they said most don't leak.

The leak we had was in that area. Water would seep under the trim strip in the areas where the caulk had shrunken. It would then run along the gap between the top surfaces to the top of the window frame. There it would run across the window frame to the inside because it was behind the caulking on the exterior of the window frame.
