I'm going for fun to see the sights and people and my other half will not fly without trolley service and inflight movies so I am flying a two seater solo ...
I'm going in my EclipsR. Takes off and lands in 150m in any temp or altitude I'll face, it carries me, 20kg of luggage, the two person tent and airmattress, inflating life vest, the remote area survival kit and it holds 110L usable with 'Fred' the second tank strapped into the back seat and I can take all 110L and remain under MTOW.
I'm then fine with taking 12 mnths to wander around in the setup. Yes I will be seeing the world pass by at 60kt in an open cockpit but I can appreciate it more at that speed and I can fly 10 hrs nil reserve between refills so can wander around without much concern of needing to always refuel when I land. Its very relaxing just wanding around looking at things. Oh and the Avmap screams at me if I wander too close to bits of airspace I am not supposed to wander through so all good there.
I know this is achievable as I have taken this set up out and just wandered around from strip to strip for weeks of holiday at a time and it works. Add the passport and a permission leave OZ and in a year I think I could get pretty much around the world and really enjoy it.
And I'd not take a modern fast RAAus aircraft as repairs and maintnenace is a pain in the butt when you are touring - simple pinned tube airframes with minimal systems are well suited to unsupported outback/remote trips. Last thing you want to be doing on a touring holiday is organising or doing a major service on an airframe/engine.
