New Zealand North and South Island in 4 weeks with camper!

About me: I am Johannes and 29 years old. For me traveling every trip is a new passion which motivates me to go to work every day :) I am very active on vacation and like to try something new. With a camper I was also not yet on the road, but car / cab / van / motorcycle or even boat driving was always me and therefore you need to worry about the driving itself at least already times no thoughts and I think the rest is now also no witchcraft!

About the camper: The camper has X sleeping places and the certification "Self Contained". -> Mandatory for "Wild Camping / Freedom Camping -> Shower / WC -> Own water and waste water supply So the goal is, I think, also clearly defined -> We want to stay as often as possible in the wild and not on campgrounds -> Beach / Outback (starry sky), in the mountains, on the mountains, at the lake or wherever we like it at the moment -> Unfortunately, it will NOT always be possible, because as I understand it, the camper must despite everything every few days times to the electricity to fill the batteries again. Of course, the fresh water must also be filled and the waste water emptied, but that goes as far as I know also at stations on the road outside and independently of the campsites. I am not an experienced camper / motorhome tourist or the like, but have a bit of experience in planning and organizing trips and therefore I'm good things that a motorhome will not overwhelm us.
