I've found that stacking items in the Teardrop is very inefficient. Easy access is a requirement in a tiny space, so stacking doesn't fit the bill.
It's amazing how much more space is created just by adding one shelf in a twelve-inch high cabinet.
Adding this shelf means we can grab a bowl, a glass, or a plate without moving things around.
And really, when I want a gin and tonic, I don't want to fumble around for it.
Adding this shelf to the overhead cabinet in the cabin almost doubled the amount of space I have for clothes. Strange, but true. Though I am a bit of a fanatical folder. I can't help it.
The same goes here, stacking sucks in small spaces.
Separate stuff out as much as possible. You'll be happier.
