Thinking of buying a Merc Sprinter spotted one online 2012 SWB 100,000 miles. Contacted an insurance company for a quote while I'm converting it and it came back £980 which to me sounds excessive especially since I wouldn't be using it but for a few trips to get materials. Is there a good company out there that understand the self build motorhome community. For 14 years I had a motorcycle trike and there was one insurance company that were great to deal with who made the extra effort. The other choice I have is to get the van delivered and not insure it until it's done. It's pretty secure with me and I could always take the wheels off !!!! Thanks guys.
