Just cuirios on what Vehical you would choose, must be easy to maintained, have lots of spares around and or easily and cheaply bought for spares in advance, I guess Must run on bio diesel.
I was thinking something from the 60,70s with no electonics, easily maintained, can get parts from scrap yards, if they have not rusted away
Thinking a jeep kind of vehcial, land rover kind of vehical.
Thanks for listening.
