Enjoy your trip, I can't add anything more to what has already been posted. We were there in June of last year and I'm planning my next trip. Namibia is an incredible country and like you, I hope to see more of it in the future.
We considered wild camping before we went to Namibia last year but quite frankly its a non starter. The camp sites we stayed in were brilliant, cheap as chips, safe, and in the case of some the profits went straight to the local community. you would have to be nuts to just camp on the side of the road, plus I don't think you would enjoy it that much.
We just returned from our second safari with Roy and Janet of Otjandaue. Had an amazing time. Safe travels
