My ‘12 is at 275k with minor issues. Def heaters went, popped a radiator, ball joints, of course brake. It’s the little things like my radio display burned out, drivers power seat not operating right now, back up sensors and a power lock on driver side rear door( maybe my fault). Engine is stock and awesome, tranny is untouched and Great and suspension was a broken main leaf( also probably my fault). All little Mickey Mouse stuff. For a six year old truck, I’d say she is doing fine.
