My cars (2005 Nissan X-Trail) caravan socket failed whilst away on holiday in Hythe Kent. Fiddled about with it myself and only made things worse. Wasted most of the holiday trying to get someone to look at it, without success. Managed to slowly limp home. And a friend pointed me to A & S Towbars at Battlesbridge. Sorry about the story but I just wanted to show that from my experience, most fitting companies just want to fit complete Towbar Systems. A & S Towbars ARE different. They care passionately about their products and service (Even though they didn't originally fit my towbar system) they were only too pleased to help me out, as I'm going away again shortly. They are a quick, efficient, pleasant and extremely professional company to deal with and I cannot recommend them highly enough. Don't hesitate to use them for your towing issues.
