This is a three phase powered box body. It has two long work benches one containing the hard wired ATR or Automatic Test Rig Designed to fault find on all ptarmigan equipments. Although the blue box fairies or systems techs as they prefer to be called spend most of their time trying to make it work after they've spilt their brew in it. Due to it's 3 phase power supply the ERV Trunk supplies all it's own AC and DC power via internal mains. This vehicle also has air conditioning and NBC Capabilities and usually works in tandem with and Electric Store Vehicle.
Both forms of ERV are robust and versatile mobile workshops, although not without their age and equipment problems.
Also as you can see with all those 240v sockets floating around they also double up as: cp's, games rooms, brew room, cinema and general w*nk palaces.
