I am contemplating purchasing a sterling Ruby caravan and have never towed before. The dealer tells me that my car which is a Vauxhall Signam 3.2 v6 petrol is above the 85% towing limit however will be OK as this is only a suggested limit and provided it does not go above 100% it is legal. I have estimated that it will run at about 93% at MTPLM. Could some one please give me a experiences at towing at this level, and do you have any suggetions.
