Devonfletch, I would hate to rain on your parade, but please be careful with E&L. At first sight everything looks fine, but I have heard and read horror stories when a claim is made. Insurance is one of those things that generally speaking you get what you pay for, which is why although a bit more expensive than others, the CC policies are excellent. Even dealers with no vested interest in who you insure with rate them very highly. Love them or hate them, the CC know the caravan business and the policies are geared to excellent cover. NFU are also thought of very highly indeed. Not cheap but I say again, you get what you pay for in most cases.
We pay extra for storage, but have never had a problem on sites. We use a lot of CLs. We always ring a new site before booking. If the people don't sound nice, we don't go. There are plenty more in the book. We always mention it's a twin, just in case of any access problems, but so far we haven't had any difficulty.
