They're are quite a few running around Reno from time to time. A local fab shop has a contract for suspension systems for different military groups and they were tested frequently outside of Reno.
A very good friend of mine even had one stored in his garage for an extended period. That was until the government agency responsible for them called the guy in charge and asked him why one of their "Trucks was in a garage on a street where it wasn't supposed to be." That's how they found out they were equipped with GPS tracking devices. A logical answer was provided and the hilux remained there for about another month.
