I think that the Camping and Caravanning club site at Clent does caravan storage and there are one or two storage sites in the Evesham / Tewkesbury area.
Hi, thanks for the response. I have found a local farm which stores approximately 100 caravans on hard standing for a reasonable annual fee. Security is provided by automatic electric gates etc and is secure, tucked away from out of site from the main A38.
