Fuses

[mountaineer]

My 2013 FFE has a very large number of fuses in three boxes, eight current ratings, and several different physical sizes/types. I haven't yet opened the boxes to see if there are any in-place spares. If not, I'm inclined to keep in the glovebox a small set of spares for at least the kinds that the two in-vehicle (not high-voltage under-hood) boxes use. Thoughts, please?

I see a small unlabeled hatch on the right side of the center console, probably poppable open with a tool. I see nothing in the owner's manual indicating whether that's the fusebox, and no other obvious place to look for the fusebox, which is described only as being under the glovebox.
