Was in the back of a dodge 2500 my buddy got from a vet. Wanted the truck but not the box and now the box has been sitting at my place for a few years in the shade taking up space. There are wires going into it and a vent on the back I believe it may have some kind of refrigerator in it but you can find that out for yourself when you buy it. It’s in pretty good condition doors and cabinets open and close pretty easily.
