Of course 6 weeks not enough but all that work commitments allow! Yes a lot of driving - 6000 miles but was part of the fun. Only about 5% was tarmac, most narrow sand, gravel, rock, mountain passes, river beds etc...
Was a bit of a whistle stop tour, but certainly great for getting a feel for those countries I know I want to go back with more time, especially Namibia.
Costs about 3500 shipping there and back. Similar cost to renting, but I dont think many of the rental vehicles would have lasted the type of routes we did.
