I always asumed that i was covered by the RAC ..
That was until i read the small print !!
Under our Recovery service caravans / trailers on tow at the time of a breakdown are covered up to a maximum overall length of 7.6 metres (25'0"). However, if it is your caravan / trailer that has broken down at the roadside and we cannot repair it, we will arrange for it to be recovered but not pay for this.
