My campervan had a flat battery because it hasn’t been off the drive for so long. The RAC came within the specified time (up to 90 minutes) and phoned to say where they were when on their way. Did lots of diagnostics, tried to jump start the battery, but it was shot. Fitted another one. No fuss. Very satisfied with this side if the business, but less so with the customer service team afterwards (see separate review).
