I'm talking all the hills on the F6 from Wollongong to Sydney, not just climbing Mt Ousley.on the BA manual, beware of redbook, not all of its figures are accurate. From memory when i was researching all manual ba-fg xr6t had a 1600kg towing limit. Clutch and box don't like the strain.
also, i much prefer the having a lot heavier tow vehicle, just imagine what its like pulling up a 2.3t trailer with a 1.5t car when the trailer brakes fail.
or even worse even if you're halfway around a bend and you need to slam the brakes, chances are bad enough of jack knifing with a 4WD, youre nearly guaranteed it in something like a falcon or commodore.
