Hi Alex - It sounds like you pretty much have your mind made up. Living in such close quarters can be "taxing" to say the least. Keep in mind that all of your personal items such as clothing, food, and other household supplies will take up a lot of space. There will not be much room for many extras. But, if you have lived in a college dorm or a military barracks, you already know this. Have you ever camped in a travel trailer or 5th wheel? Perhaps you can find one to rent and stay in a few days and that will give you a general idea. Whatever you decide, best wishes and good luck in your pursuit of such a noble profession.
