Yup, it is another of the Icelandic Ambulance Snow Tracs.
The ANARE cabs are not wider than traditional cabs, they mount in the same places as the traditional cabins but have a windshield that tips in the opposite direction, and the side windows are simple sliding windows. The Icelandic Ambulance retrofits have the original cabs taken off, and a wider cab fitted to them that extend to the outside of the storage rails so the interior of those cabins are much wider than a traditional Snow Trac cab. That extra wide cabin on the Icelandic Ambulance Snow Tracs allows them to carry a passenger who is laying down on a stretcher. Take another look at the ANARE Snow Tracs and you will see they are the traditional width.
