I have a 1998 300tdi Defender and am thinking about buying a decent size caravan. I know the weight can be up 3500kg but has anyone any experience pulling a 4 berth twin axale job? I have looked at a few tow car / caravan match sites but sometimes I put in a caravan and it says 'not a good match'. I don't understand why a beast like a Defender has a problem with any trailer. I have pulled a car transporter with a 2.3 ton Jeep on the back with no problem, so what's this with caravans? I know a twing axle will be more stable and less likely to snake but what else to I have to consider. Any ideas will be gratefully received. TIA.
