Towing caravan (Pitmedden AB41)

Would love a towing caravan to use. Must be sound and waterproof. My husband and I have been together almost 19 years and we have never had a holiday as money is tight. I have to work two jobs just so that we can have a car. My husband is disabled and unable to work. The caravan would be loved and used by my daughter and son and their families, as well as my brother an his family. It would bring joy to all the kids. We live in a bungalow and when family come to visit there is no room for them to stay. We have to put a tent up in the garden which is not suitable in the winter months. If you have a caravan that is doing nothing, we will all love it and enjoy it. So please consider my plea. Thanks for reading.
