my rocker panels are completely gone... dissolved... nothing but air under there now. The rust has spread up towards the front and rear of the cab as well at the lower hinges of the doors, and it's eaten away at the lower rear door fixed latches.... it's beyond repair at this point. The door skins around my door handles are toast as well, both door latches had ripped out so I made some custom aluminum plates that mount inside bolted to the latch mechanism to hold the door handles on as there's nothing to hold onto anymore. Plus about 6inches of the lower skin on my tailgate has dissolved away as well. My bed is starting to break through from the rust as well, I was just loading some stuff in the bed a few days ago and it collapsed from my weight from rust under the bedliner in one spot... totally rusted out under there too. I have my 40 year old '84 Chevy Silverado crewcab dually that has been sitting outside for the past 8 years in an open lot (the motor seized up when the oil pump seized on my way to work one day, I ended up selling the engine, and no place to work on it, so it's just been basically abandoned outside in the elements), and it has less rust than my 14 year old Raptor. The Raptor is great, but the body steel (I use that word loosely) is junk, it's incredibly thin, probably was insufficiently galvanized, and is just a junk body. The chassis is great, powertrain and drivetrain great, I've got 225,000 miles on it... but the body, is junk. So, not surprised you're having rust issues. And it will spread fast too.... I'd sell it now while you have the chance, I waited too long.
