78-597: A kitchen , a bathroom, and one or more beds. RVs can range from utilitarian – containing only sleeping quarters and basic cooking facilities – to luxurious, with features like air conditioning (AC), water heaters, televisions and satellite receivers, and quartz countertops. RVs can be either trailers that are towed by vehicles or vehicles that drive themselves. Most RVs have one level, but there are also some with two levels. To save space while traveling, larger RVs often have slide-outs or canopies that open up when parked. Self-driving RVs can be categorized into pushers, which have

117-414: A GHT hose to a BSP fitting, or vice versa, will damage the threads. The connector threads are not tapered, and do not seal against leaks. Instead, a pliable rubber or plastic gasket (often ambiguously called a "garden hose washer") seals the connection against leakage. A variant of this gasket also incorporates a fine-meshed metal or plastic screen to filter out small particles of dirt that may be present in

156-545: A burgeoning industry that would continue to develop over the subsequent decades. Prior to WW2 a number of other countries developed their own small-scale RV manufacturing industries including Germany, Australia, New Zealand and the Netherlands. Germany had a particular focus on small, lightweight caravans towable by low-cost automobiles whilst Australia developed 'pop-top' caravans with good ventilation, ample water storage and high ground clearance. During WW2 RV production

195-454: A flexible hose is connected to a drinkable water supply, the spigot or tap should be fitted with an approved backflow prevention device , to prevent contaminated water from being siphoned back, in the event of a pressure drop. Many water suppliers require this, and plumbing code may legally require permanently installed backflow preventers. Special hoses designed to leak throughout their length are sometimes used to gently distribute water on

234-565: A hotel room. They may even decide to tow their car from the back of the RV so they can use that to travel around more easily when they reach their destination. Although the most common usage of an RV is as temporary accommodation when traveling, some people use an RV as their main residence. In fact, one million Americans live in RVs. In the United States and Canada, traveling south each winter to

273-502: A lawn or garden. These hoses have either many small holes drilled or punched in them, or are made of a porous material, such as sintered rubber particles. These "soaker hoses" are a simple, low-cost, substitute for a drip irrigation system. These differ from traditional hoses in that the inner membrane expands when filled with water, much like a balloon. An outer cover protects the delicate expandable membrane from punctures. Such hoses "grow" when pressurized, and shrink back down when

312-474: A long-term expense. This is similar to home vacation rentals but is cheaper and also offers the flexibility of itinerary planning. While it is legal in all of the United States to live in an RV, there are laws regarding where and for how long RVs can be parked. Some owners fit solar panels to the roof of their RV. It is possible for RV users to live off the electrical grid while still having access to internet, making remote working feasible. Usage of RVs

468-445: A typical garden hose can mate with the female connector on another, which allows multiple garden hoses to be linked end-to-end to increase their overall length. Small rubber or plastic washers (often confusingly called "hose washers") are used in female ends to prevent leakage, because the threads are not tapered and are not used to create a seal. Most garden hoses are not rated for use with hot water; even leaving certain hoses in

507-400: A warmer climate is referred to as snowbirding . In Australia, the slang term for a retired person who travels in a recreational vehicle is a "grey nomad".

The female thread is abbreviated FHT (for "female hose thread"), and

624-624: Is the predominant term in other English-speaking areas. The term " hose " is also used for other types of flexible, water-carrying tubes such as fire hose used by fire departments . Garden hoses are typically made of extruded synthetic rubber or soft plastic , often reinforced with an internal web of fibers . As a result of these materials, garden hoses are flexible and their smooth exterior facilitates pulling them past trees, posts and other obstacles. Garden hoses are also generally tough enough to survive occasional scraping on rocks and being stepped on, without damage or leaking. Each male end of

663-788: The Grande Diligence of Prince Oldenburg (1896) and the De Dion Bouton trailer of Monsieur Rénodier (1898). The first steam-driven motorhome was the Quo Vadis (France,1900) and the first gasoline-driven motorhome was the Passe Partout (France, 1902). The first recorded powered motorhomes in America were the 'camp cars' of Roy Faye and Freeman Young of 1904–06 (a 1904 Rambler , 1905 Thomas Flyer and 1906 Matheson ). Lightweight tent trailers were especially popular in

702-618: The McMaster Camping Car (US,1889). Camping-vehicle In the 1890s, US RV pioneers self-built timber 'houses on wheels' for health, leisure and hunting purposes. The most widely reported of these were those of Morgan Lasley and his family. Horse-drawn RV use declined after the First World War as many horses were killed during the war and automobiles became cheaper, more powerful and more widely available. The first powered RVs were steam-drawn trailers from France including

741-633: The RV Industry Association. The recreational vehicle industry around Elkhart is part of a large network of related transport equipment companies, including utility trailer makers and specialty bus manufacturers, who source from the same supply chains. The industry has taken hits from US tariffs on steel and aluminum and other duties on RV parts made in China, from plumbing fixtures to electronic components to vinyl seat covers. Tariff-related price hikes forced manufacturers to pass on some of

780-615: The US from 1911, thanks to improved roads , new national parks and the affordability of tow vehicles such as the Ford Model T . At the other end of the price scale, luxury touring limousines, developed in France by De Dietrich in 1904, were built in small numbers in the US by Welch (1909) and Pierce Arrow (1910). The first US RV club, the Tin Can Tourists, was formed in 1919. The first known, recreational fifth wheeler

819-511: The US) were usually converted goods trucks and were heavy, noisy, inflexible and expensive, restricting their use to the wealthy or self-builders. The 'one box' RV was not seen in large numbers until the small, lightweight Volkswagen Kombi of 1950. During the 1920s and 1930s, caravans (travel trailers) became the dominant form of RV in the UK due to their low cost, weather-resistance and flexibility. There

897-422: The advantage of interconnecting without distinction between "male" and "female" connectors, Some connectors also incorporate an "autostop" feature. This is an internal valve which is shut off by water pressure, and it is opened only by connecting a fitting or appliance; thus, disconnecting a hose fitted with this adaptor will automatically stop the flow of water. This eases connecting and changing appliances without

936-524: The engine at the back, and pullers, which have the engine at the front. Generally, pushers use diesel fuel, while pullers use gasoline. The first recreational vehicles were horse-drawn. They evolved during the second half of the nineteenth century as adaptations of vehicles used for other purposes, including public transport caravans (UK, also known as stage wagons ), gypsy vardos (Europe), living vans (UK), ambulance wagons (US) and sheep herders wagons (US). The first, currently-known, purpose-built RV

975-442: The flowing stream of water. The purpose of this filter is to intercept debris which could otherwise clog the small openings used to disperse a spray of water from various garden sprayers and sprinklers. Adaptors made of metal or plastic are available to interconnect GHT, BSP, NPT , hose barb , and quick-connect fittings. In the 1980s, the use of quick-connector systems became increasingly popular. These are fittings that attach to

1014-464: The hose and or screw into common hose connectors and equipment, allowing hoses and accessories to be easily connected together using a snap-fit type system. The first plastic connector was invented in the UK by Hozelock in 1959, and the style has now become a de facto standard throughout Europe and the wider world, compatible with and imitated by many other manufacturers. A differently-designed hermaphroditic quick-connect hose fitting made by GEKA has

1053-400: The increased costs through higher RV prices, which in turn has contributed to slower sales. Shipments of RVs to dealers fell 22% percent in the first five months of 2019, compared to the same period a year earlier, after dropping 4% in 2018. RVs are most commonly used for living quarters while traveling. People may choose to take a road trip in their RV and use the RV to sleep in, rather than

In other countries, a British Standard Pipe (BSP) thread is used, which is 3 ⁄ 4 inch (19 mm) and 14 TPI (male part outside diameter is 26.441 mm or 1.04 in). The GHT and BSP standards are not compatible, and attempting to connect

1209-412: The need to shut off the water first. In 2014, it was reported that use of common garden hoses in combination with spray nozzles may generate aerosols containing droplets smaller than 10 μm, which can be inhaled by nearby people. Water stagnating in a hose between uses, especially when warmed by the sun, can host the growth and interaction of Legionella and free-living amoebae (FLA) as biofilms on

Hoses used to carry potable water are typically made of NSF International -listed polymers tested and shown not to leach harmful materials into the drinking water, such as the plasticizers ( phthalates ) used in polyvinyl chloride (PVC, or vinyl) hoses. As implied by the name, garden hoses are commonly used to transport water for gardening, lawn care, and other landscaping purposes. They are also used for outdoor cleaning of items such as vehicles, equipment, building exteriors, and animals. NSF-approved hoses may be used for connecting drinkable water to recreational vehicles and trailers. Whenever

1365-673: Was halted in most countries except when required as accommodation for military personnel or essential workers. Between 1945 and 1960, RVs flourished in many western countries as disposable income and leisure time grew. Dedicated RV parks were established to cater to the needs of both short and long-term RV users. Improvements in RV technology including batteries, fridges, gas cookers, toilets and lightweight construction techniques dramatically improved RV comfort levels. More powerful gasoline and diesel engines allowed RVs to increase in size, weight and speed. Regulations were introduced in many countries to control how RVs were manufactured and used. In

1404-961: Was likewise a travel trailer boom in the US in the 1930s as automobile production-line manufacturing techniques were used in travel trailer manufacturing to meet growing demand from recreational users and those seeking low-cost housing during The Great Depression . Self-built trailers were highly popular in the US during the 1930s and travel trailers featured in a number of Hollywood movies including Mickey's Trailer (1938). The 1920s and 1930s, saw some influential, maverick builders construct innovative RVs in small numbers. These included Bertram Hutchings (UK, 1930–39, streamlined caravans), Charles Louvet (France, 1924–34, aircraft-inspired, coach-built motorhomes and trailers), Noel Pemberton Billing (UK, 1927, Road Yacht motorhome), Glenn Curtiss (US, 1918–30, Adams Motorbungalo, Curtiss Aerocar, Aero Coupler hitch) and William Hawley Bowlus (US, 1934, aluminum monocoque trailers).
