G'Day Sickgm,
To MySwag.
I guess the size of camper depends on how many you have in your crew and if your family is going to get bigger or not.
Here are the
Floor Plans for the camper.
We have an older Swan & we are a family of 5, so it is the Goldilocks size.
We are constantly modifying it as our needs change.
And that's were the fun is.
To Free camp, it depends how long you plan to stay in the one spot for.
Things to get would be, Solar panels and a twin battery system, LED lights, Long Drop, Shower tent, Solar shower bags or the 12 v pumps that suck out of a buck, Enough water to last you, We carry 180lt in two tanks, so we can go a fair while, Carry enough beer is the problem, A second fridge/freezer would be a good idea for long stays of over a week. I sure there will be others with different ideas or more suggestions.
We've been camping for a few years now and we still don't have everything we need or want, but we have the basics.
You can only do what you can afford.
Hey at lest your out there having a go.
Hope you enjoy your time here.
Happy and safe travels.
