Thread: Cunningham Highway?

Can’t answer the gradient question, can advise you shouldn’t be towing anything until you have run the engine in.

Thats only just over GVM isn’t it? Although I didn’t realize modern motors needed running in after a rebuild.

Tuck in behind a B-Double crawling up the range, you’ll only be doing walking pace.

It's not overly steep but long. If you're concerned you could go via Ma Ma Creek or the new second range crossing to Toowoomba then Warwick.
Ma Ma would be my choice, it slower but has points of interest.

States in the factory manual to not tow for first X kilometres. You could do it, being nice and it should actually help bed the motor in if not thrashed up the hill.

As said,it’s long not steep,just take it easy.

I towed 3.2T up the old Toowoomba range,the D4 thought it had the anchor out

Ian,what is the new Toowoomba range run like?

Haven’t tried it yet,hoping it takes 1/2 hour or so off the run to Dirranbandi.

It'd easily save half an hour in a truck, maybe twenty minutes in a car. It's nowhere near as steep as the tollbar, a steady climb coming out at Charlton, so not climbing to the altitude of Rangeview.
I've come down in the Disco, locked in 3rd and didnhave to touch the brakes to maintain the speed limit.
If you try it before Christmas, it's toll free, but watch out for the average speed cameras and flash for cash.

It's no problem, done it several times towing, just change down and keep the revs up a bit.
We recently towed up a 31% slope on the Daintree in low-second, so compared with that the Cunningham is easy.

But you're not running in a new motor, Mike.
