The Vehicle
Problems to be dealt with are: heat, 19,000′ Andean passes, water, off-road capabilities, MPG/KPL, diesel preference, carnet de passage and getting rid of the vehicle after a one-way leg. Oh and there is the Darien Gap. If you have experience with this kind of choice do advise I need help here. (PS Both Carnet de Passage & Darien were red herrings, the first unnecessary the second impossible)
