Other Fuel System Tank Assembly problems of the 2006 Toyota Tundra

I've owned the truck for a year bought on Dec 2019 3rd owner. I see that mines not listed as recalled for frame rust but I'm not sure why when the gas tank looks like it going to fall off and seems only critical sections are severely rusted like the gas tank and where the rear shock absorber sits. I could only see these spots now because they are hard to spot places where the frame joins.
