We cook inside. Single bowl sink which leaves an adequate if not substantial work area between sink and range top.
Microwave is suspended from upper lockers which frees up space beneath. 18"X26" standard baking sheet over the rangetop is used as counterspace for cleanup after the gas burners are no longer needed. The five food containers that we store in the hanging locker (2 large size, 3 medium) contain all dry and non -perishable staples, cereal, snacks. They come out to play on the bedspread aft for the cooking end of the gig. We also have a 30"X31" table in the dinette up front. One can indeed sit down and peel potatoes. We don't cook fish or cabbage and maybe we're not that fastidious over food smells altho we might become more so if Yogi were to express an interest in the leftovers! Physically all the problems of a confined space are accentuated by high population density so of course the singletons, the empty nesters, and other lonesome types cope more easily. I might roast sausage and sliced taters in a "dinner packet" in wood coals once in a blue moon but I'm not planning on hauling around a 1 1/2 ton, miniatured simulacrum of the quotidien home kitchen and then trying to stuff it with all the stuff you'd need for a summer kitchen or BBQing.
