there are hundreds of thousands of 4th gen 4runners on the road in winter climates that dont have holes in the frame or need patching or are rusting that bad from the inside out that fast. mine is from this area with ~150k miles & while it did have some failing factory coating & heavy surface rust, the frame is still 99% solid & no signs of heavy scaling or pitting rust inside the frame.
my post was mainly to say there is definitely somethings that can be done to help with or greatly stop rust. but i also agree that some frames were neglected or had other outside things make them rust worse than the large majority of others.

I don't think his truck has ever been off road except for the occasional dirt road. He's not the type. He did do all he thought he could do to keep rust away. I don't know why some rust and some don't but obviously it happens often enough and going above and beyond doesn't always keep it away. Maybe it's the brine crap they put on the road here. Mine had to be patched in several places, it had the factory black goop on it but it's not as bad as some of the pics I see here.
