Large station wagons no longer exist in the US market. The biggest one remaining is probably the Volvo V90, which is a nice car but can barely fit 5 people, and if you put a dog in the back then there's no room for cargo. It's also too expensive for most families; several large SUVs are actually cheaper.

Minivans are a good option for some families. But they suck for towing trailers, and the ground clearance is terrible if you ever have to drive on a dirt road.
