I am lucky enough to be associated with I Dream Africa which do Angolan trips,various trips in Namibia, Damara land, Kaudom and four different Namib trips, the best one of the lot probably Solitaire to Walvis (4 days), The most extreme trip dune trip is probably this one,doing dunes slip face up of up to 160 metres in height -- you hit the bottom of dune at 140-150kmh and change gears from 4th right up to 1st just to get over !!
This is really the most extreme trip and can be adjusted on the move to cater the abilities of the drivers and vehicles. Not recommended for diesels though. If you are interested, i have organised a few extreme (and it really is extreme) trips for the land cruiser club and can get you better prices per person for these trips. Here are a few pics of previous trips:Doing 155 kmh on the gps starting to climb a 185m meter dune
