This year's Caravan Salon Dusseldorf, one of Europe's largest exhibitions of mobile homes and caravans, was attended by not just the residents of the German city of Dusseldorf, but also those from other parts of the country and the Continent. The show was held from Aug 29 to Sept 6.

Many middle-aged couples and elderly people brought their dogs along to the fair, where some 130 companies set up stalls to show and sell their recreational vehicles.

While RVs are common in Europe for leisure travel, foreign companies are now looking at China as a market with potential.

"RVs are not only about business, but also about dreams and lifestyles. China is perfect for them due to its beautiful scenery, vast land and good roads," says Stefano Bonometti based in Italy, the area manager in China for German brands Hobby and Fendt, owned by Harald Striewski.

Chinese are fond of exploring nature, he adds.

"If RVs are popular in other parts of the world, why not in China?"
