G'day Debbie and Geoff and welcome to the forums.
In respoce to your query ... I have a camper trailer (CT) that goes just about everywhere with me. What we do is set it up in either a caravan park or camping site and then use that as our base. It gives you a comfy place to come back to plus warm showers.
If you literally want to leave civilisation behind and 'rough it' then the caravn may have to be left behind and a CT taken. Or even a tent. We carry a tent with us even when we have the CT as we would go to a caravan park for say a week and then maybe head off on a fourbie track for an overnighter.
Eitehr way a caravan or CT shouldn't limit your exploring too much. I found it to be just the opposite.
