I was lucky enough to have been both on the driving and wrench-bending end of the M561 Goat. In spite of a lot of the stated recollections above, my time with the Goat (other than the noise) showed that it was a vehicle that could literally climb a tree if the driver knew what he was doing. Place the transfer in low, lock in all six wheels, place the front bumper (or the piece that extended in front of the winch) against a stout Texas tree, and slowly lett he clutch out. The truck would push the cab forward, then up the trunk, while maintaining the rear four wheels on the ground. After our experience, we would laugh and drink lots of adult beverages!
The noise was inescapable, and this was the first vehicle that (in my experience) we had to wear hearing protection with. The lucky co-driver could wear the radio headset as an inetrim fix.
It could swim, climb, wallow through mud and sand like nobody's business,,, Quite a vehicle. Overall, yeah, impractical as hell, but then, so was the idea of riding on an M151A1C with a 106mm RR, thinking we could really slow down the Russian hordes as they would drive to the Rhine. In the 70s, you used what you had, keeping in mind that we were designed and equipped to fight the last war, as is usually the case.
And yes, I would love to have a kit of the Goat, something more substantial that the Schmidt vac. When Valley Plaza Hobbies was still located in Valley Plaze (North Hollywood, CA), they stocked Schmidt, and I remember seeing one on the shelf. Shame I didn't buy one then.
