UPDATE: **Status Unknown** Was $5000.
This one has a strange story. I don’t know if it is an XM-408 or not, but I did run across a manual for a 6×6 Mutt on eBay (see bottom).
“Bought the Mutt a military vehicle auction. Took it to shop to get running. They removed the engine and claimed it was stolen. So it has not engine and possibly other thinks missing. It was a ambulance in a past life. Unknown who put the 6 wheels on. Could have been the collector or it could have been a test vehicle in the US or Israeli army. I wanted to get it up and running to drive around on some property. It is not street legal. It would be fun to have hauling people around a farm or ranch. Takes a flat head ford army jeep engine.”

There’s also a reproduction manual for the M-151 6×6 on eBay:
