I used to see a bit of these in Fort Jackson, during my time of Hell Week and then 9 weeks after. They were re-building the old section of the base.

The marina owner bought it years back at a govt. auction and uses it now to lift boats out of the water, for the winters. 1. The rear end. 2. 3. Cheers!
