How much rust is too much?

Hey guys,

I’ve got a 2018 Tundra I’m looking to buy, and while I was underneath I noticed some rust on the frame and shocks components (pics attached). I know these trucks are kind of known for frame rust, but I’m trying to figure out if what I’m seeing is just surface rust or something I should be concerned about long-term.

 

How long do you plan to keep it? Any plans to nurse it back to good health? Why not find one that isn't already in need of saving from the rust monster?

 

That looks fine, if you’re in the north.

If you’re in the south and have higher standards against corrosion, I’d pass on that one.
