Actually trucks down here rust out real fast due to the salt in the winter time they use for the roads.
When we moved here in 2013 from AK, we brought back a really clean '96 Z71, within I'd say 3 years, cab was going to shidt.
I really like those 300's. When I worked at ANC international, most of tugs had those things. Had to eventually install the FI upgrade kits and get rid of the old 1 bbl carb. Rampers did not know how to work the choke. Then after they flooded it, they figured they could fix. I got sick and tired messing with carbs in the middle of January cuz of stupidity.
