2006 Manual Diesel 3.0L boat towing

[GQtdauto]

Our 2002 model struggled with a caravan of about 2700 odd kgs and it is an auto , hills were a big problem

With a big boat behind my old DI I found I had to use low range to get up steep boat ramps without riding the clutch.
3000kg would be a bit of a struggle with any hills, my CRD will hold its speed going up hills with car trailer & car, but acceleration is slow when the speed limit changes or to overtake.
