Americans with small families own a car. If both parents are working, they usually have two cars. When the family is larger, they will sell one of the cars and buy a van (住房汽车).
A small car can hold four persons and a large car can hold six persons but it is very crowded. A van can hold seven persons easily, so a family with three children can ask their grandparents to go on a holiday travel. They can all travel together.
Mr. Hagen and his wife had a third child last year. So they sold their second car and bought a van. They thought it would be more convenient for them to go out together.
Americans call vans motor homes. They always use them for holidays. When a family is traveling to the mountains or to the seaside, they can live in their motor home for a few days or weeks. All the members of a big family can enjoy a happier life when they are traveling together. That is why motor homes have become very popular.
