Sorry to ask yet another question! We are seriously considering buying a Sterling Europa 460 (2007) caravan to tow with our new shaped Honda CR-V. As we are caravan novices we now need to buy everything we need. We are thinking of buying Milenco Aero towing mirrors as used in Practical Caravan Tow car awards. So does anyone have any recommendations about whether we need Grand Aero or Aero mirrors - and one flat and one convex or 2 flat or 2 convex mirrors. Help please?
