In the second of three programmes about travel and why we do it, Lynne Truss talks to Jillian Moody about her experiences of travelling across the world in a campervan with her husband and three young daughters. The family bought a second-hand campervan prior to the trip which had no shower and no toilet and after a terrible first night, reality took its toll as they realised their itinerary would have to change. They were faced with many challenges en route but after 38,000 miles, there's no doubt it was a life-changing experience for Jillian. Producer Sarah Bunt.
