Hi, we are researching caravans and hoping to look at some this weekend. Any advice on choosing a starter 2 berth caravan would be appreciated. We are going to look at an Abbey Expression 470 2 berth 2003, Swift Challenger 480 SE 2002 and Bailey Pageant Monarch Series 6 2008. We would be using it for touring, so would like it to be light. I was wondering if the upholstery on the older models would still be comfortable for sleeping. Also, would people recommend buying from a dealer rather than private? Thanks in advance.
