G'day Dennis, Are you intending to travel solo, or with a companion?
If travelling for a few days only, perhaps a Toyota High Ace with an awning affixed would get you out there. They can be made quite comfortable for small trips, and easily made into a defacto camper van with little effort.
If you decide you like the lifestyle there is always a ready market for campers, you can upgrade to a purpose-built RV later on.
