Came across it in a industrial estate in North Carlisle on driver training there when I was at Eddie Stobart's depot.
Assuming it is used as a trainer on a regular basis, it could explain its sightings in the North East, especially with Sandy Lane being just to the north of that photo. I can't remember the most recent test routes unfortunately.
