In Europe, wagons built to live in, rather than just to carry persons or goods, were developed in France around 1810. They were used in Britain by showmen and circus performers from the 1820s. Romani people only began living in caravans (vardos) circa 1850.
The covered wagon that played a significant part in opening up of the interior of the North American continent to white settlement, beginning circa 1745, was a type of caravan. A well set-up wagon provided its occupants with living quarters as well as a means of transportation for themselves, and their supplies and equipment.
In Canada, the earliest motorhomes were built on car or truck bodies from about 1910. By the 1920s the RV was well established in the US, with RV camping clubs established across the country, despite the unpaved roads and limited camping facilities.
