G'day stujaz, I had the exact model your talking about and towed my 2012 jay of swan outback my thoughts:
1. From a towing pov on the road it towed great (you will need a WDH) plenty of power, and returned on average around 12-13 ltrs per 100.
2. But once you hit any type of dirt, or grass especially backing the swan it was hopeless. You just get wheel spin and it became dangerous.
I got rid of kluger & replaced with my old 80 series.
