I guess I have been stranded on account of something breaking in the G only once.
I been left unable to start by ordinary means once.
When turning the ignition key, a little piece of metal broke off that is suposed to make the switch turn. To activate the startermotor there is a slight springloading, so it could not overcome that. Preheat and oil light came on, to it was just a matter of push starting the truck and all was fine. It's a manual transmision and non-eletronic OM602 diesel engine so unless a disaster strikes I can allways get going.
I have been stranded, unable to get out of a ugly situation by own power once, but that was 100% my own fault.
Misjudging the flow of current and twice the waterdepth I expected, we attempted to make a rivercrossing on Iceland. Unlike the 50+ streams we had crossed in the previous 3 weeks, the current dug deep holes in the riverbottom and we hit one of them.
Got tossed on the right side (where snorkel is located) so fast I did not have time to shut off the engine. Hydrolocked the engine, conrod no. 1 got bent in a S shape.
Fair amount of sheetmetal damage, needing new fender, A panel, front and rear door.
We needed a bit of assistance to drag the truck out of the river and transporting it the 2000 km home. That was a dumb driver moment and no fault of the truck.
