In the United States, the term "van" refers to vehicles that, like European minibuses, are even larger than large MPVs and are rarely seen being driven for domestic purposes — except for "conversion vans". These possess extremely large interior space and are often more intended for hauling cargo than people. Most vans use body-on-frame construction and are thus suitable for extensive modification and coachwork, known as conversion. Conversion vans are often quite luxurious, boasting comfortable seats, soft rides, built-in support for electronics such as television sets, and other amenities. The more elaborate conversion vans straddle the line between cars and recreational vehicles.
