The next day, the remainder of the walls including the galley/bunk divider went up.  The sides of the galley were not originally insulated.  I ended up with a bunch of extra rigid foam so I filled those voids.  It won't make a huge difference structurally but it might keep your dry goods a little cooler when summer camping.

The three voids in the top half are for the galley pantry.  There will be an interior shelf towards the bunk and a divider wall on top of it.
