HI SCOTT
Ok It's a show pony, but they are very expensive even by Australian Standards It will be in the family for at least seven to ten years,
Drives are or can be very steep as mine is if you view the angle of the above photo on the last shot, The Merc has no problem going up it is just the start point from flat to a straight 45 Degree angle so the dam bar hits the ground.
I must say that is a very impressive hitch you have, as I can see you have nurtured the rust with the greatest of care over the years, sort of matches this Old Truck .
Well you have to admit to the similarity, of the two!

Interesting you have your system in reverse to mine isn't it low looks like the nuts a plow for digging up the tar?
And Hey great to see the dead vegimite on the back, goes to show what a Sprinter can pull Richard
PS Love to see them injectors valves and bore ,just to see how clogged up they were.
