TG drives the VW Amarok in Africa

Phone for help? Not a chance. There's no mobile phone signal here: even if there were, what would you tell the rescue services? "Hi, Namibian RAC? We've broken down. Badly. Where are we? Er, Namibia? More specifically? No idea, sorry. I can see... sand. And rocks." There are no towns here, few signposts. And if your car has any propensity towards mechanical failure, these roads will find it: loose-dirt tracks that veer in an instant from thick sand to rock-hard corrugation, with nausea-inducing humpbacks and dog-sized boulders thrown in for good measure.
