Thank you so much everyone, I really appreciate you all taking the time to let me know your thoughts. I have a lot to think about, but now even more keen to do this.
I will keep researching, asking questions and looking at different options, but I think towing something would suit us best, as long as it's easy for me to set up. I loved that little gadget that helps reverse, but I will be doing a towing course as well and looking into the possibility of doing a 4wd course. I don't think that we would be doing any serious 4wd ing, but maybe some easier areas that are still close to people, as I am mindful that it's just the 2 of us and my lack of experience - for now! I plan to get our set up a few months before leaving so we can do a few practice runs first on the weekend.
I'm sure I will have a million more questions! We are sitting down this weekend to do some more planning.
Thanks heaps,
Kellie
