Thanks to Diplostrat for pointing out that the Boltons' South America trip is ending early due to mechanical problems. Current issues include poor engine performance at altitude (probably the result of a botched repair of fuel injectors earlier in Uruguay), broken shock, failed water pump, auxiliary fuel tank leak, and broken fuel tank support bracket. Kym was able to perform bush repairs on all of the issues, but confidence in the vehicle has sunk. As Kym puts it,
"It has been a hard decision, however in light of the vehicle's unreliability we cannot continue into isolated places that we enjoy."
The EarthCruiser vehicle has traveled close to 120,000 km (75,000 miles) on rough unpaved roads and two wheel tracks on 5 continents.
The Boltons will continue to explore Chile and Peru for the next couple of weeks. The EarthCruiser will be shipped back to Australia in mid September. I'm guessing, but I expect they will return with a Scrubmaster, the Iveco 4x4 camper built by Kym's new company, Travel Trucks.
