If you are with the caravan club you can get the Mayday green flag cover which will cover the Eriba and the car. A lot of car Break down policies will only cover you if the car has an issue. When my Familias brakes failed Mayday were called out, I managed to get the brakes sorted, with a caravan engineer, however Mayday green flag were going to take my van home for me at the end of my holiday if I couldn't get them fixed. They will also take you to your destination if you brake down on the way and then bring you back if it cannot be fixed, so you don't miss your holidays..
