Sorry for your loss of the truck. Might have been better to not have found it.
Impound yards are nothing but legalized robbers.
The same thing happened to a family that was looking for a lost person. The police found the truck and his body sadly. But they didn't call the family to recover the truck. It just had a flat tire on it. The police had it towed to an impound lot and it cost about the same amount the next day to get it back.
