When we started traveling almost 4 years ago we had a major breakdown after climbing a range. The next day we started out and the bus just started to loose power and stopped on the highway. After getting help from mobile mechanic got into town then they found algea in the fuel and bypassed all filters to get us running, when I questioned this action they replaced and re-plumbed the filters. A month later injector pump and injectors had to be replaced, had another mobile diesel mechanic come to us and remove these and send away to have replaced, when he returned a month later to fit new ones he did not time the pump. After he followed me into town so I could pay him cash I expressed my concern that it felt sluggish and under powered, his exact words were " get the auto checked, it could be slipping" For the next three years we drove the bus clocking up 20,000 ks with the pump timing out by ten degrees. I have had the timing set by a heavy diesel mechanic with thirty years in the industry and we have truly have a new bus, fuel economy has improved heaps and so much more power and no accelerator needed to start cold.
It has cost us over $8000 and has been one huge learning curve.
Travellers seem to get taken for a ride.
