Both PMR and DUD are no problem for 76 200 or 300 performance wise.
But last time I checked, there was no means of getting off the aircraft in DUD and getting the aircraft out. I may have this wrong, as I remember it, there was a lack of suitable tug. So you cant push back from the airbridge. There was no stairs either, so you couldnt stop on the apron and let people out before departing under your own steam.
