My mum took her 2000 Tundra with 82k to a indy garage for a state inspection. The mechanic had never seen so much rust on a frame. It is flaking apart in sheets. He called the Toyota dealer who wants to see it and document it to send to Toyota customer care. I have seen it and thought wow that looks rough but I have never owned a full frame vehicle. I will post pics when I get a chance. Anyone out there here of any issues. I see some internet posts but majority are for Tacoma.
