Is there a seam under the center molding of my roof?

[bartletts]

I have a 2008 Fleetwood Yuma, and I'm wanting to make sure the seams and fittings are all caulked well before the rainy season starts here in Oregon. (Believe it or not, it doesn't rain much between July and October here.)

My aluminum roof has some corner protectors that are caulked, and a piece of molding down the middle of the roof. Is there a seam under the molding? Should I caulk around the molding? I don't want to caulk something that shouldn't be caulked. The owner's manual I have is silent about the issue.
