Blast from the past: Ford-ing!

I culled some paperwork this morning and found two photos that were MIA. This is "Tuffy" the F100, fording a river some-where in the Northern Territory.

Unlike Elmer, "Tuffy" didn't have a reserve fuel tank.  He had a 44-gallon drum mounted within the rear canopy area. 

My father rigged some kind of system to siphon the fuel.  I'm not sure how it worked, though my brother and I used to ride in the rear with the drum - with seating provided by a former bus seat, screwed to the floor!  Obviously life was very different back in the 70s!  (The mini-bike on the bull-bar was powered by an old lawnmower motor, so worked on a pull-start cord - when it worked).
