After glamping in our Flying Cloud for a year now, I think the wife has it down when it comes to figuring out what works for her. She's a great cook and loves simplicity.
This is our top drawer
There's a flatware caddy that's on top of another flatware caddy to maximize the vertical dead space.
The next drawer has an expandable drawer that rests on top of the drawer frame that can slide back and forth to get to items below. We used duct tape to keep the expandable drawer at the desired size...works every time! This drawer can also be fitted horizontally too but this works better for my wife. She bought it at an office supply store. Good for storing small and frequently used items.
This drawer we use for food storage items - ruler box to store different size plastic baggie, and collapsible bowls and their covers.
Our drawers may not be the same dimensions as yours but I hope this helps you out.
