The first question is this: What do I actually need?
The model I am using is my friend's trailer. She verified the interior is 6.5 x 10 or 65 square feet. The bathroom version (yeah, for the sake of argument we are going with that) includes two closets, understorage on the seats, and some small cabinetry around the sink (apparently there is no storage on the outside of the unit):
For example, today's test would be kitchen and cooking:
The unit come with a 1.9 sq ft refrigerator and a two burner propane power stove. As you can see, not a lot space for either food or cooking items.
But realistically: how many cooking items do you need? Pot to boil, check. Small frying pan to fry, check. Tea pot (well, for me anyway), check. Colander? Maybe. A smattering of measuring spoons and cups. And some plates, cups and silverware to eat off of. In other words, possibly the contents of that drawer above the refrigerator (if you packed it right).
Reality check: what do we have currently? Literally, a kitchen's worth of cooking utensils and pots and pans and various and sundries (that does not include the food. Seriously. We have more storage committed to items we use to cook than food we cook with).
Am I advocating a complete abandonment of everything we have in our kitchen except for two dozen items. Not at all (and in our case, this might provoke a revolt. The cooks of our house actually use a fair amount of them). But what I am trying to get to - at least to myself - is what do we really need versus what do we really have?
Why? Because, frankly, stuff costs money. And space. And money to pay for the space. And that money, space, and money could be more profitably used on something else.
This has actually been a fairly entertaining mental exercise - and easy for me, as I can pretty much get by on almost nothing vis-a-vis cooking. Wait until we get to books - that will be another story...
