People often contrast "stupid" from "ignorant". "Stupid" means a lack of intelligence, an inability to comprehend information. "Ignorant" means a lack of information.
"Uninformed" means pretty much the same thing as "ignorant". It has a milder tone, but that's about the only difference.
These definitions were found on Wordnik:
chest:
- A sturdy box with a lid and often a lock, used especially for storage.
- The part of the body between the neck and the abdomen,
enclosed by the ribs and the breastbone; the thorax.
trunk:
- A large packing case or box that clasps shut, used as luggage or for storage.
- The body of a human or animal excluding the head and
limbs.
I found it interesting that the words were practically synonymous in two very different senses.
As to your comment: dictionaries do not seem to be very specific when defining "trunk" and "chest", that's partly because, much like the storage items themselves, the words are very versatile.
Quite often, you'll find a descriptive word in front of chest: treasure chest, tea chest, tool chest, medicine chest, e.g.
There are other ways the words differ, too: some might call a bureau a chest (or chest of drawers), and many of us carry a key that opens the trunk of our car. I suggest visiting the Wordnik pages for expanded definitions and example uses.
As for using the words in your original sense (to describe an object such as the one depicted below), I think you were onto something when you said we'd be more likely to travel with a trunk than with a chest, but I might use either word to describe the object in the picture.

The first four examples and upscale have a roughly identical meaning, which is expensive and of high quality, being typically patronized by the wealthy and notable. (Admittedly I had to look up tony, because it's not common in AmE.)
The remaining, exclusive means something slightly different.
Exclusive implies that it is difficult to get a reservation due to a degree of discrimination on the part of the management. Usually this is due to the extreme popularity of the restaurant, leading to a situation where the remaining tables can only be gotten by people who are of some sort of elite status (celebrities, wealthy, etc.). This is a ploy by the management to make their restaurant seem more desirable by dint of their famous clientele.
