My S-in-L has a 3000, I think it's an early 2000's he bought used. The drive train and transmission have been reliable and have plenty of power. he has replaced all of the wiring between the firewall and dash. Also the dashboard. he had frequent and spurious electrical problems that nobody could isolate so he said "Ferk dis chit" (he is a real mechanic, not just on Saturdays that are pretty) and eviscerated that sucker. Now it runs good and no random electrical ghosts. Never did find the cause. I like driving it. Plenty of guts, even with 4.5 tons behind it and it tracks well at highway speeds.

So I'm kind of thinking about a similar truck, but I couldn't handle the job of full replacement of all that wiring, so I'm kind of shy about that one. Reminds me of the ghost wiring issues I had with my E320, w124......
