I think most likely it is a Velvac mirror as stated above. We had a 1995 Monaco Windsor and had to replace a mirror and it was a Velvac. I believe almost all of the motorhome manufacturers use these mirrors.
Ouch sorry your machine was damaged. There is a Monacoers Yahoo group called Bill D's Monacoers and also a Monaco graveyard site called www.Visonerv.com that has parts from crashed units.
