your told wrong then mate, there is no way on this planet that a fourtrak will ever ever tow 3.5 tonne and be safe doing it, it would push you straight off the road, 110 Defender or a discovery is the only way to go, I have a few trailers at work and they are plated at 850kg, basically it allows me to put 2150 kg's on the trailer, now Plenty of people go on about the Landcruiser being the dogs danglies, but when you move vehicles up and down like I do you get to know quite quickly what cuts the mootard, the Landcruiser is grand until you really put the weight on and they too get pushed around,
