Welcome to the forum, Sam.
Check out White Arches at Rusden, we've bought 3 caravans from them and can't fault the service we've had over the years. We've had manufacturing problems galore, but they have always been prompt in contacting the manufacturer and swiftly getting various problems, some of them serious, dealt with. They have clean and bright showrooms containing caravans from Swift and Bailey and a very extensive area outside with used vans of varying ages. They also have a cafe and a small childrens play area outside, too.
