⇨RAC will recover the van if the car is at fault, but if the problem is the van then the answer is no , they do not recover, this is whether you have the manufactures RAC or C&CC Arrival..
The above is not what I infer from the following, copied from the C&CC website:
* Off road assistance - including recovery from a UK campsite (provided vehicular access is permitted)
* No width or length restrictions for caravans/trailers/motorhomes of proprietary make
* Covers breakdowns on the caravan and trailer not just your vehicle
* Covers you as a driver or passenger in your or another vehicle (non-commercial vehicles, excluding certain vehicle types)
* Arrival Return - taking you to your UK holiday destination and back home again if your vehicle can not be repaired (When Recovery has been taken as a membership option)
* ReUnite - brings the vehicle and caravan/trailer together if they are separated due to a breakdown
* No European supplements for trailers and older vehicles if taken as an option
Some of this is presumably optional with different levels of cover. I rely on this so I hope you are wrong Robert ;-)
