I realize we are talking a small space but I believe it just is more common to separate the kitchen from the living room areas. The "kitchen" incorporates the sink/stove/fridge with the dining table and the "living room" contains either two couches or a combination of couch and chairs/desk.
Since we travel alone 99% of the time (no kids/grandkids to accomodate) we specifically looked for a rig a single couch with a movable recliner and fixed desk. I think it's all personal preferrence.
