Motorhome repair North Yorkshire

We need a major damp repair to our motorhome and would like to hear of any recommendations for workshops in North Yorkshire (preferably near Thirsk). Two possibilities we've found are Caravanman at Brompton-on-Swale (near Richmond) and Caramed at Northallerton; does anyone by any chance have experience of either of these, please?
