We are hoping to buy our very first caravan and have spotted what appears to be a well-maintained 1998 model ABI Dalesman 450CT. Does anyone have one already that can give me any pointers on what I should check for on this particular van? I know Practical Caravan did a write-up on it in Oct 2003 but I don't have time to get a back-issue and nothing appears on the web. Any advice would be appreciated.
