A little bit of interesting information on these ambulances. A few years ago, I contacted TACOM with the contract number to see if there was any information available on them. The history officer was not able to find anything on the contract itself but did tell me the prefix indicates the purchase was made by the Army, not the Air Force. Many years ago when talking to a friend, who had some knowledge of Chrysler's history with the military, about the first of these ambulances I had contact with, after a friend had purchased one, he thought they may have been part of a program which resulted with the M880 series adoption.
