Does that include on the undulating country either side of the big hill or just the hill itself? One of the steeper pinches is at the bottom. You will probably go to the lowest gear there. You will come back up a gear or two and maintain that until the other steep pinch just before Piper's Lookout. You will drop back to the same gear (or so) as the bottom steep pinch. From there you will gradually go back up to your highest travelling gear as you brest the top. That is unless you stop at Pipers's Lookout, which is worth a stop (there are picnic tables and dunnies there last time I went up.)
You will probably make more gear changes on the undulating country than on the big hill itself.
Peter D hi.
My comment was all tongue in cheek, one old ex truck driver to another.
But I would be interested in his thoughts, if he is anything like me it will be, "just another hill".
I am sure it will be fine, after dragging 62.5t around on an old Scotts S-Line with a 420hp Series 60, I reckon I can manage
I have been up Brown Mountain before, back in about 1991 with jut a 4by, wife and 4 kids
