Could you actually live long-term in a van?
All depends on what you're happy with!
No problem living in a van - I spent years living out of a 36 inch sleeper, so a 14'6" van should be sheer luxury!
Well, by the time we clear all the debt, selling the house should leave us with around $150k.
The place we're planning to setup a base in, has dwellings starting from around $20k up. Rates are only a few hundred per annum, and the Shire Council tends to pretty much leave you alone.
Whilst it is a long way to the nearest capital city, the Simpson is just up the road, and the Flying Doctor calls by once a week.
What more could you want?
