Yet to be named... ‘78 K10 Suburban

[Old65C10]

We are very lucky where I live. We don't get much rain, less than 9in per year. No salt or brine is ever used on the roads and there is always super low humidity. So my truck is completely rust free.
I even have a 65 C10 that is very solid, only rust is in the front fenders where they collect dirt and it sits and rots, ever 60's Chevy truck has rotten fenders.
At least most of that work can be done and you wont have to paint, just heavy undercoat.
