Most modern dictionaries give one of the meanings for the word caravan as "a camper equipped with living quarters". They in turn give one of the meanings for camper as "a recreational vehicle equipped for camping out while travelling". In Europe, wagons built to live in, rather than just to carry persons or goods, were developed in France around 1810. The covered wagon that played a significant part in opening up of the interior of the North American continent to white settlement from about 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, plus 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. In Australia, the earliest known motorhome was built in 1929. It is recognized by both the National Museum of Australia and the (Australian) National Motor Museum as being the first motorized caravan in Australia.
