I had SN 2043 (M422A1) from 1977 until about 1987, it's in the Philadelphia area somewhere with it's second civillian owner. The only two complaints I had then were that parts were hard to find and you always need a supply of front hub center bolts, and no heater. It was designed for the jungle and you had to put chains on the front wheels to steer in snow...if the snow was more then 12-15" deep, you were screwed, as the front differential guard would ride up on the snow and take the front wheels off the ground with it... AND you then couldn't back up as the differential guard would catch in the snow and act as a brake....
Other then being noisy, it was good for 40+ MPG when it did choose to run... I miss it quite often now, but it got a very good home!
Besides, with 4 wheel independent suspension, it would go up side slopes that a Unimog couldn't climb (100% diagonals), and if you did get stuck three guys could just about lift you out of the mess.... HOO
RAH!
