Before You Die: Go 4x4 in the Kalahari by Mark Eveleigh

Now you can take on the Kalahari, too, but on your own terms: travelling light, third millennium style. All you need is a Land Rover Defender expedition vehicle, fitted with long-range fuel-tanks, 10-gallon water containers and a high-level exhaust (in case of the unlikely event of a flood). At night you sleep out, as nature intended - with just the flimsy walls of a predator-proof rooftent between you and the Kalahari night.
