Motorhomes usually have sleeping spaces for 2-8 people. Each sleeping space is either fixed or converts from another part of the motorhome's interior, usually a fold-out sofa. A kitchenette area contains cooking equipment. The type of equipment included differs depending on the motorhome make and model, but generally a kitchenette has a stovetop, oven, refrigerator, and sink. More luxury models may also provide a microwave. A small bathroom with a shower, sink and toilet is usually also located in the motorhome. On smaller motorhomes, the toilet may be of the "cassette toilet" type, which is a kind of portable toilet or container-based toilet. The toilet sometimes swivels to provide extra room and can be accessed from outside the motorhome for easy emptying. Larger motorhomes usually have a separate shower cubicle.
A motorhome also has a cab area with a driver and passenger seat. These seats often swivel to become part of the living space. A dinette area provides a table and seating space typically used for eating meals. A lounge may also be included, consisting of either a U-shaped sofa located in the rear of the motorhome or a side lounge.
In the United Kingdom and United States, the word motorhome is commonly used. On occasion, other synonyms are used, such as motor home and motor caravan.
In Germany, a motorhome is referred to as a Wohnmobil. In Sweden, the term husbil means motorhome. In France, a motorhome is called a camping-car. In Italy, the term camper is used to mean motorhome in general, and the term motorhome refers to Class A motorhomes in particular. Spain and Portugal use auto caravana or auto-caravana. In the Netherlands and in Poland, the term camper is used.
In Australia and New Zealand, the term campervan is frequently used for smaller vans, either with a low top or high top that do not have a toilet and shower. In New Zealand, the term housebus is frequently used for larger motorhomes.
The origins of the motorhome date back to 1910, when the Pierce-Arrow motor company introduced the Touring Landau model at the Madison Square Garden auto show. The Pierce-Arrow's entry was specialized for 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 27 feet (8.2 m) 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.
Motorhomes can be roughly categorized into three categories:
There are many different motorhome layouts available with each manufacturer offering a range of options. One layout innovation that started in 1999 was the development of a slide out or slide room. As seen on the floor plan of the Thor Motor Coach, a slide out is an area that increases the square footage living space of the motorhome. These slide out(s) extend to allow for more living space while parked and retract while driving. As with most innovations, the original slide outs were considered a luxury item, whereas they are now standard on most of today's[when?] motorhomes.
