Had an acquaintance with a large fleet of military vehicles and trailers tragically pass away. I had discussed purchasing a M817 military dump truck from his collection before he passed. When we got there we found the dump truck engine was completely locked up. So I picked out another truck to try...

1970 XM818 6x6 tractor truck, with a Cummins 250 non turbo, 5 speed transmission, and a two speed transfer case.
