I'm not sure what happened to this vehicle, I'm not even sure of the vehicles identity. The truck looks to be an M39 5-ton. Judging by the damage, the driver and passenger (if any) had a run-in with a Viet Cong RPG-7. The fifth wheel of a 5-ton truck was one of Charlie's favourite targets. Convoy protocol calls for recovery of the cab unit then the trailer. Usually, there was only one tow truck per convoy, so the trailer would be left behind for a separate recovery operation. Needless to say, the trailer would be empty upon recovery.
