We are planning to drive to Botswana from Cape Town in our own vehicle (Land Rover Disco 4 or Fortuna, haven't decided yet). Is it better to try and get hold of a roof top tent or to hire an equipped trailer or put our ground tent up and down? We are worried about the maneuverability of a trailer. We plan to go to CKGR and Moremi. Any advice would be much appreciated.
