the camper in mind—providing cargo compartments for camping equipment and even an on-board toilet. In the 1920s, individual builders and manufactures began to convert panel trucks and buses to be used for camping. Designers patterned these "housecars" after airplanes, boats, and buses. RV production was halted during World War Two and would not resume for the domestic market until the 1950s. When production did begin again, designers began grafting trailer bodies onto truck or bus chassis. Raymond Frank gave these housecars their contemporary name of “motorhome". Following a pattern common in RV history, in 1958 Frank designed and built his first motorhome so his family could take vacations to Florida and the mid-west; it was long and mounted on a Dodge chassis. Soon afterwards, other campers took an interest in the design and asked Frank to build them one too. By 1960, the Franks had sold seven motorhomes, and decided to open Frank Motor Homes, Inc. the next year. With the stylish fiberglass construction and contemporary color palette, the Frank motorhomes became an acceptable option for 1960s suburbanites who wanted an RV but scoffed at the travel trailer. Soon other firms began to manufacture these mainstream motorhomes. In 1958, one of the most recognizable names in motorhomes was launched—Winnebago. Under the direction of John Hanson, Winnebago began to produce nearly all of their motorhomes' components other than the chassis. In ten years, Winnebago had grown from 415 employees to 1,252 in 1969 with over $3 million in sales. While Winnebago was the market leader, other companies were also growing. In 1969 a total of 23,100 motorhomes were sold. While the gas crunch of the 1970s drove many manufacturers out of business—including Frank Motorhomes (then known as Travco)—today, the motorhome market continues to be strong. In 2014, 43,900 motorhomes were sold in the United States. Categories Motorhomes can be roughly categorized into three categories: Class A (also known as integrated) A Class A motorhome often has a reputation for being the most luxurious and expensive of vehicles. It has a solid body with the driving area integrated into the standard living accommodation. This style of motorhome will have a large and expansive front window which offers a good view of the road and surrounding landscape. Berths convert from lounge or dinette areas. Class B (also known as semi-integrated) A Class B motorhome is also referred to as a low profile or
