How's that diesel truck research going? I've thought about getting into auto repair as a hobby, but wrenching on modern cars would basically be my day-job with added wire fiddling.
I learned that most diesel cars and trucks are still dependent on electronics for fuel injection and also have a higher minimum-quality of diesel.
The prepper nerds seem to advocate for Cummins 12-valve engines from the 1990s or the Toyota 1HZ.
There's a whole lot of old diesel LandCruisers out there. I'm guessing that's the sweet spot for it still being a normal car that mechanics can maintain while still being comfy and looking cool.
