I have just had to cancel my insurance with Comfort (Aviva) because they have a clause that means if you leave the vehicle un attended for more than 48 hours its not covered, I was leaving at a Marina on the west coast of Scotland whilst I go sailing for a week, but they said unless it was in a secure compound with cctv it can't be done, no amount of assuring them that the people up there would keep an eye on it and that in 15 years they have never had an issue would get them to allow it so I had to cancel and move to a different provider. surely lots of camper owner have outdoor hobbies that have similar situations, I did say that I thought the van would be safer in the wilds of Scotland than the long stay car park at Gatwick
