Germany's Volkner Mobil creates custom luxury RVs. The vehicles come fitted with a fully equipped kitchen, a bathroom, a bedroom, and a "garage." The German manufacturer Volkner Mobil, run by married couple Gerhard and Stephanie Volkner, makes custom luxury RVs. So he decided to build one himself, using the chassis of a truck, Stephanie Volkner said in an interview with Insider. The cheapest version Volkner Mobil offers costs 425,000 euros, with most models costing between 1.1 million and 1.8 million euros, which is around $1.07 million to $1.75 million, Volkner said.
