Hey mate. I have used mine to tow a mates boat (big cairns cat), a camper trailer and various nissans
) and found it loved to tow, specially in the sand.
Unsure of the ratios as I am at work but I have found my engine very reliable and have had no problems with it what so ever. Depends on what you are towing for fuel economy etc. Mine is pretty good with the stock tyres on and can still get the 10-11litres / 100km with the muddies on.
I am thinking of selling mine as I need to downgrade and buy something cheaper to get the missus off my back but can't bring myself to do it !!
