In the Christmas episode, "The Santa Experience," the Pickles, Devilles and Finsters all go up to the mountains. It appears they take one car, which is a minivan. How can 8 grown-ups, four babies (plus Angelica) a dog, food, luggage, and the Christmas presents and decorations all fit in one car? It would have to be an enormously huge minivan for that to be possible, or most likely, an RV.
