"FDNYBuff97", the above picture is different from the first picture posted on this thread. If you look close to the first one it has the letters "FSD" (Fleet Services Division). And the picture you posted is no doubt FDNY/EMS Div 2 as you say.
But just so you know, the FDNY has MANY of these vehicles. They all look the same. I have a photo of one similiar that has "EMS Div 4" on it.
