Hi
Be very careful when obtaining quotes, we had this same problem and some of the policy wording states that if you have the van stored on farms etc they should have perimeter fencing etc etc and the insurers dont tell you that when they give you quotes, therefore, if your van does get stolen then your not insured if the place you have it stored doesnt have the security mentioned in the policy statement. We opted for the caravan club as you can store your van whereyou like they do not place any unreasonable rules. They werent the cheapest by any means but as they say you get what you pay for. I previousle used insuremycaravan.co.uk who were cheap, but, i took out their breakdown cover and what they didnt tell me was they had a restriction on the length of the towing vehicle and ours was over that length!! if we had a breakdown we wouldnt have been covered!! I now read the policy facts and wording before I take out any cover, its very tedious but, when you are talking about a large purchase of a new van you really should consider these facts before deciding and ask the right questions? Hope this is useful for you?
