Looking for a Place to Store Our Caravan

We are a quiet, friendly couple living on a housing estate, and we're looking for a safe place to store our caravan – ideally within around 30 km of Callan. We travel nearly every weekend, so having the caravan close by would be a big help. It can be a private property, a farm, or a campsite – we're open to suggestions and easy to get along with. Of course, we’re happy to pay for the space. Many thanks:)
