I bought this old caravan 6 months ago as a project to up-cycle. 
I have done a few in the past but due to a change in circumstances I don't have time to do this one. 
It is solid and dry. These are the 2 main components I look for when buying them. 
It is actually in perfectly good, serviceable condition so could just be used as it is.
I don't seem to able to find the key, so it will need a new door lock. (I will keep looking while this listing runs)
I do not know the age of it.
I am very happy for it to be viewed or I can send any specific pictures if you want.
I have added a photo of an upcycled one, for inspiration.
It measure 18.5ft not including the tow hitch
Any questions please ask.
