A comparison of Schutzbrief assistance packages from ADAC, ACV and ARCD highlights differences in caravan coverage when the towing vehicle breaks down. ADAC does not include return transport of an undamaged trailer to Germany; the caravan is left at a safe location. ACV covers the caravan if the towing vehicle fails and repair takes longer, providing return to the place of residence. ARCD explicitly covers the caravan without its own defect, including return transport. Key factors include whether cover is person- or vehicle-based, towing limits and whether a replacement car has a tow bar.
