I got a 16 with 130,000 my son has my old 12 with 250,000 and I had a 10 that was totaled with 165,000. Oil changes air filters about it. Also had to replace bulb sockets on 12 and 16. But that was 44 bucks both trucks. It goes to the turn signals. I guess that’s all I could rate as a weak link. Other than that just drive the piss out of them.
