Hi Andrea and Gary.
Welcome to the Group, and congratulations on ordering KEDRON caravan.
Before you visit the factory, compose a list of questions. You might find many of those will be answered when to go there. I suggest the main thing is to get a firm understanding of the specifications and any extra things you want. Also, ask Graham to send you some photos of the various build stages.
Other than that, enjoy the experience and comradeship the Group can offer.
All the best.
Cheers from Pete
