Somerset caravan storage

Hi all, I'm hoping to buy a caravan asap, i have just bought a car to tow it, tow bar, number plate, mirrors etc, but before i buy the caravan i need to find somewhere to store it. We are moving house to somerset next year so it would be nice to have it stored there so that we have a base to search from. my problem is finding somewhere to store the caravan, i have contacted a few storage facilities but they seem to be fully booked. i realise now that being winter people have put their caravans into storage buy i'm hoping there is someone out there that can point me in the the right direction. by the way we intend to keep the caravan once we have found the right property with the intention of touring around the west country....and beyond!                                                                                                                                         Thanks Dennis
