On this trip, we came across two large off-road recreational vehicles in a parking lot at one of the trails in Utah’s Arches National Park. The one pictured here appears to be built on a Unimog chassis. While it doesn’t look like a motorhome, off-road RVs like this include many of the same features found in other motorized RVs.
Unimog
The Unimog is a range of multi-purpose tractors, trucks and lorries that has been produced by Boehringer from 1948 until 1951, and by Daimler Truck (formerly Daimler-Benz, DaimlerChrysler and Daimler AG) since 1951. In the United States and Canada, the Unimog was sold as the Freightliner Unimog.
Due to their off-road capabilities, Unimogs can be found in jungles, mountains and deserts as military vehicles, fire fighters, expedition campers, and even in competitions like truck trials and Dakar Rally rally raids. In Western Europe, they are commonly used as snowplows, municipal equipment carriers, agricultural implements, forest ranger vehicles, construction equipment or road-rail vehicles and as army personnel or equipment carriers (in its armoured military version).
