UNICAT builds RVs for travelers whose idea of a trailer park is Death Valley or the Kalahari. And they don't build campers only. For the right price, the company will create just about any kind of mobile base station, for which an interstate highway is just a suggestion, like the Terracross and the Maximog. [Thanks to David for the tip.]
