Started to notice rust on my frame lately as its spring and I'm starting to wash and clean my truck more often. It seems to be mostly on areas where it was welded. I don't even know if its worth the hassle of trying to get the dealership to fix it. They will likely just say it's because of the salt from the winter.
Just another thought, I don't really care so much if the rust is only cosmetic and won't cause issues in the future. That being said, where I can see my frame in the rear wheel well is rusted, has anyone considered using a bedliner materials to cover just that area?
