Ceiling hooks to support hanging pantry?

Wow, I really appreciate the feedback, especially taking time to post photos! I think I'll take the advice of calling the manufacturer first. The liquid nails idea seems tenable, unless the manufacturer objects (they may do so just to cover themselves, of course). Maybe they can at least tell me where I can buy the "optional kitchen pantry" their literature talks about but no one knows how to get!

See you on the road somewhere!
