I would bet on it being safe to tow. Five of them left the service, so were replaced as a fleet, rather than due to damage or neglect. I'm pretty sure these would have been JTF, as those super swamper tires were not normally on the run of the mill HMMWV stuff. It did say that the CADC guys couldn't close the tailgate.
There is a large tank in the trailer...unknown what was in them. I suspect just water. It won't be staying in the trailer once it gets home. So if it's liquid manure you have, fill away.
