Just a quick update to say thanks for the input. We took the van to John, who did a fine job on it for a fair price. There were quite a few bits that needed doing, including the damper and two wheel bearings. Driving to Heswall gave me some towing practice (we're brand new to it).
John and his wife are really lovely, gave us some helpful tips and made a good brew too.
We're a step closer to going away for its first trip. Hurrah :)
