Hi there,
Travelling for the last 3 years in a 2009 Fuso FG 84 4X4 Motorhome I can confirm and agree 100% with the comment above. the 150 fuso dealers world wide mean little (once you turn up most are nt even interested in helping you!) except when you like to use the dealer to do your oil change etc for very high prices. Once we left Australia we lost all warranty and support. In Africa-Europe-Russia and now South East Asia spare parts are unavailable for this model. So you require a Credit card and a account with DHL or FEDEX. after 150000KM Off Road Travel I am also convinced that this truck is not a perfect OFF ROAD EXPEDITION VEHICLE. The mercedes above or a MAN prior to 2007 (Euro 3) are much better choices and world wide service and most parts are available. Remember sooner or later you do require service with any truck as things brake or fail, once you use the 4WD the way it should be used OFF ROAD. Having said this the Fuso Engine is perfect but my view with the light Fuso truck is that other components are not designed for the harsh environment such as parts of Africa Northern Russia, Siberia, Mongolia and South Asia.
Hence service and breakdowns are frequent. Unless you have a credit card and DHL account, waiting for parts to be delivered via the dealer could take up to 3 months. ( We have been quoted 5 months for Fuel injectors from Japan by Fuso Benelux to arrive) Hence the only option was DHL at high cost plus all the duties. No experience with Cummings or international bu both brands I have seen in Africa. Cheers Fearless.
Just some experiences of world wide parts availability.

Basically I concluded its nigh on impossible to predict what will fail and carry all the "what if" parts. After that its a combination of having reliable info, reliable contacts, a reliable way of delivery, and time. I'd go as far as suggesting carrying information about the vehicle (and camper) is more important than carrying parts.
