They didn't go to GP- whenever something is turned in, it goes through a process, offered to other DOD, then other feds, states, etc finally there is a period things can be pulled by states for non profits etc. This is how he got them. Runs a huge at risk youth camp. The kids love the military trucks and going for rides, learning how they work, etc.
I got involved years ago and provide technical advice and help him find parts, TMs, etc.
He holds onto and uses the trucks for a few years, then sells them. Helps fund the camp, and allows him to get newer/different trucks.
