That's cool stuff, I couldn't survive a day in those conditions in Australia, barely in my own contry 😅.

I think you should definitely get that shopping cart for yourself, if you think it will make your experiences a lot nicer and smoother, what's a few hundred smackaroos for a better time going forwards.

The campsite picture you've shown here, looks actually pretty cozy and I see you even got some solar panels setup, very modern.
