I have the opposite problem. Trucks seem to last forever in the PNW, if far enough inland. We simply have no issues with rust. Been looking for an SR5, or other mid-sized older truck. But I want it to be a life long PNW truck. Which if not sold by a private party has gotten difficult. I'll ask the question at a dealer, and all of a sudden they don't know anything about where it came from. Real easy to tell, since plates in Oregon are issued for the life of the vehicle. Brand new plate--- its from out of state. Check the under carriage and sure enough, there is substantial rust everywhere. Then one can find the little tells, its a Montana or Idaho, or some eastern seaboard, area. During the great used truck famine of 2021-2023, I think dealers shipped in many a truck from these areas. Thinking the noobs in the PNW, not use to any rust issues, wouldn't check.
