Is the biggest difference between these two at least on the outside,the generator vents on the a1,I’m in the process of doing a Vietnam early version?
Yes, externally. There were internal changes to the engine and other systems. The M88A1 added the Little Joe generator on the right rear of the cabin. The M88 did not have the door with louvers nor the exhaust on top of the bump out on the right rear of the cabin.
Greatly appreciate the answer and photo,thanks
