If you have the intention to travel in 3rd world countries you should not take a diesel truck with modern emission control systems. Either take a gas engine or a diesel without emission control systems. The second question you should decide before looking at specific trucks is the size and weight of your cabin. If you want to live full-time in it you need enough space to live even in bad weather and you need plenty of storage for clothing for 4 seasons, recovery gear, tools, spare parts, food, toys etc. Add at least 30 gallons of water, a large fuel tank (at least 700 miles), perhaps propane, grey water tank etc and you get a fairly big and heavy cabin. Even if you use lightweight material you should expect 4000+ lbs wet and at least 12 ft length. Only once you have a feeling for the size and weight of your cabin you can start looking for a suitable truck.
Both the fuso and the Dodge Ram cummins can handle all that. And run on any diesel in the world. Sooo the Question is Dodge Ram or fuso.
