Hi, was reading your post ,re might sit in your van in your drive way,I had to post back a reply to you...We own some land down the coast from where we are based at the moment,we have one of those Amish type sheds built on it ,we were staying down there one brake from work with caravan parked next to shed, Along came this council guy telling us we could not have the van parked there as it was not connected to the building ???? But i can park beside a public road but not on my own property.I know your situation is very different to our's ,but just thought i would let you know how country is being over regulated with so many differing rules from state to state on every thing from Rego/ insurance/licenceing, and the  differeing reg,s inside the work force.That is one reason a lot of people from  one state to the next state  cannot get jobs in the mines if not living in that state .As they have all the required tickets in the state they live in but , not recinised in another state. But the goverment allows workers from O/S . Hard to fatherm all this out.
