Its no secret that Toyotas make horrible frames when it comes to rust. I've seen lots of Toyotas that are four to five years old with a significant amount of rust. Its unfortunate issue with Toyota.
I was watching that truck too. I love the color. I felt it was too screwed around with, higher mileage, and overpriced. You really confirmed that even further. It a shame that someone will still end up paying top dollar for it eventually and not get their monies worth.
