I run from rust......straight to OK, TX,CA, GA, or any state that doesn't use road salt and buy good used vehicles. I'm happy to fix some sun fading, etc. instead of rust. After working on cars for 25 years in rhe midwest, I NOPE right out of that scenario.
I've had decent success in the past 10 years doing so. If you get a clean truck to start with and rust proof the heck out of it they really last a long time here. But, it's a yearly process that takes just a small amount of time and dedication
