My car is covered under Nissan roadside assist. I get an all singing and dancing cover up to 3 years old and every year that I have a Nissan service. Nissan use the RAC. I have just had a conversation with the RAC. My caravan would be recovered with the car if the car breaks down but If the caravan breaks down it would not recovered. He told me a caravan is fully covered if joining the RAC through The Caravan and Motorhome Club.

The CC recovery deal (Mayday) is with Greenflag, not the RAC afaik.
