Is it the actual weights of car and caravan or the theoretical maximum weights that decide if your legal to tow.Have had licence many years Ford Galaxy 04,4000kg train weight,2510kg max vehicle weight,Indiana 1500kg so 10kg over .Thats not serious I dont suppose but was looking at Eldiss Tornado 1600kg,dealer said it was fine,2000kg tow limit etc but the train weight would be well over (110kg)fortunately havent put a deposit on it
