Land wanted to rent for campervan

Hi im looking for a site to rent to live in a campervan with my dog.Im a decent clean living Irish guy but am finding it difficult to find rental accomodation because I have a big(friendly)dog who I will never seperate from and have decided to give van life a try if I can find somewhere suitable to park up.Im willing to pay up to 500 per month for half an acre of land.My preference would be in wicklow or south Dublin.Thanks for reading
