On September 24, 2007, we saw this big boy parked at one of the trailheads in Arches National Park. There was another large offroad recreational vehicle parked nearby. Later we saw both vehicles again, parked at a picnic area.
As best as I’ve been able to find online, this RV is built on a Mercedes Benz Unimog frame.
