Liliya's Pink Cloud RV

In the U.S., about 85 percent of recreational vehicles sold are manufactured in Indiana,[4] and roughly two-thirds of that production in Elkhart County, which calls itself "the RV Capital of the World", population 206,000. The industry has US$32.4 billion annual economic impact in Indiana, pays US$3.1 billion in taxes to the state and supports 126,140 jobs and US$7.8 billion in wages, according to the RV Industry Association.[5] 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.[4] The industry has taken hits from U.S. 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 the increased costs through higher RV prices, which in turn has contributed to slower sales.[4] 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.[4] Usage Class-C motorhome[6] Class-A motorhomes[6] 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 a hotel room. They may even decide to tow their car from the back of the RV[7] so they can use that to travel around easier 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 the United States and Canada, traveling south each winter to 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".[8] Living in an RV has become increasingly popular. In fact, one million Americans live in an RV.[9] While it is legal in all of the United States to live in an RV, there are laws around where you can park your RV and how long it can be parked for in certain areas.[citation needed] Some owners fit solar panels to the roof of their RV.[10] Usage of RVs is common at rural festivals such as Burning Man.[11]
