Dan is driving his 2011 Jeep Wrangler all around Africa, and WOW, he's made it the most capable Jeep I've seen

he has a 2 year plan to explore the perimeter of the continent, and he's blogging about the experience http://theroadchoseme.com/

I hope he's getting a discount on Amazon, because he has spent thousands there to gear up and outfit his Jeep with everything expected to be needed for day to day living, and getting unstuck, and fixing flats, extra lighting, and extra space via a pop up roof. http://theroadchoseme.com/the-jeep

His previous expedition was Argentina to Alaska, and it took 2 years. Without GPS, and he seriously recommends to NEVER do that. That trip was in a 2000 Wrangler that cost him $6k

With all that experience of driving around the world, he is a force to behold in his prep work and knowledge of the right gear, and amounts of it. Mini fridge with dual Optima Batteries, and solar panels to charge them. None of it is connected to the Jeep for independent camping without having to run the engine.
