They look like awesome rigs. It's the rig price, when one starts jumping continents, one has to be prepared to walk away from their vehicle, both physically and financially.
The emission equipment issue doesn't bother me, people are traveling the world with later model diesels without their emissions hardware removed. When someone reports via social media that they are stuck with emission related issues, the hundreds if not thousands who see the post spread the word. Now hundreds if not thousands are reported to be having emission related problems due to higher diesel fuel sulfur levels. It would be nice if the sulfur levels were at least consistent. The numbers range from 15ppm, 50ppm, 300ppm, 500ppm, 2000ppm and 5000ppm.
Its worth repeating, on later model diesels with a DPF its important to use an engine oil that meets low ash content specification API CJ-4.
