yes I have been across loads... you need docs for the trailer i.e Natis clearence such as the log book thingy or if financed a cross border letter from the finance provider. The same applies for the vehicle... you need xborder letter from the bank who in turn require proof of comprehensive insurance across the border. just make sure that the docs for the trailer are in order same as vehicle i.e listed on insurance etc. you can get insurance at AA in musgrave or at the border. obciously you need the towing triangle on the vehicle and the trailer, you are also meant to have ZA stickers but i never but mine on.
If there are going to be 2 drivers make sure they are both listed on SA insurance and Moz insurance NB if other person is driving in Moz and you get caught
What actually happens at the border is wildly different between Ponta, Siteki etc
Hope this helps ..
I phoned the guys re the comp and there is space I am now a bit hesitant because the guy I wanted to go with didnt get the pink ticket and I am not to keen to go alone.. from a driving point of view if a bearing goes or such like it is a mission with no other vehicles around
Cheers
