B-61 at the National Pike spring show, Brownsville, PA, May 17, 2009.
Driver was aware of the side angle when dumping, it’s a scissors lift.
He had prepped the slope a bit with their D4.
We watch it work every year, most recently August 2016. Still beautiful, and running fine.

I guess this is why they call it a Bulldog.
